Naskh (tafsir)

Naskh (نسخ) is an Arabic word usually translated as "abrogation". In Islamic legal exegesis ("tafsir"), "naskh" is a theory developed to resolve contradictory rulings of Islamic revelation by superseding or canceling the earlier revelation. In the widely recognized and "classic" form of "naskh", an Islamic regulation/ruling ("hukm") is abrogated in favor of another, but the text the "hukm" is based on is not eliminated.
Some examples of Islamic rulings based on "naskh" include a gradual ban on consumption of alcohol (originally alcohol was not banned but Muslims were told that the bad outweighed the good in drinking), and a change in the direction (the qibla) that should be faced when praying salat (originally Muslims faced Jerusalem, but this was changed to face the Kaaba in Mecca).
With few exceptions, Islamic revelations do not state "which" Quranic verses or hadith have been abrogated, and Muslim exegetes and jurists have disagreed over which and how many hadith and verses of the Quran are recognized as abrogated, with estimates varying from less than ten to over 500.
Other issues of disagreement include whether the Quran (the central religious text of Islam) can be abrogated by the Sunnah (the body of traditional social and legal custom and practice of the Islamic community), or vice versa — a disagreement between the Shafi'i and Hanafi schools of "fiqh"; and whether verses of the Quran may be abrogated at all, instead of reinterpreted and more narrowly defined — an approach favored by a minority of scholars.
Several Quranic verses state that some revelations have been abrogated and superseded by later revelations, and narrations from Muhammad's companions mention abrogated verses or rulings of the religion. The principle of abrogation of an older verse by a new verse in the Quran, or within the hadiths is an accepted principle of all four Sunni "maḏāhib" or schools of "fiqh" (jurisprudence), and was an established principle in Sharia by at least the 9th century, (though since the 19th century, modernist and Islamist scholars have argued against the concept of "naskh", defending the absolute validity of the Quran).
An abrogated text or ruling is called "mansūkh"; and a text or ruling which abrogates, "nāsikh".
Definition and etymology.
In the Arabic language "naskh" () can be defined as abolition, abolishment, abrogation, cancellation, invalidation, copying, transcription, according to the "Hans Wehr Dictionary of Modern Written Arabic".
As an Islamic term, there is a lack of agreement among scholars on what exactly "al-Naskh" is, (according to several sources). 
Disputes over what defines "naskh" include 
Another issue was how broadly naskh should be defined, with early Muslim scholars having 
including things that later scholars did not consider "naskh", such as:
Definitions of "naskh" given by Islamic scholars include: 
Scriptural basis.
Quran.
According to non-Muslim scholar of Islam John Burton, "no single verse" in the Quran "unequivocally points to the naskh of any other verse", (nor does any "irreproachable" hadith identify "any one verse as having either undergone or effected naskh"). Islamic Modernist mufti Muhammad Abduh (1849-1905) also stated “the Quran nowhere announced that verse so-and-so is naskh, or that verse such-and-such is Mansukh.”
Many of the verses believed to indicate the principle of naskh do not contain any form of the word naskh, i.e. any word with the triconsonantal root n-s-kh, instead they use "in place of" ("baddal"), "effaceth " ("yamhua"), "withdraw" ("nadhhabanna" لَنَذْهَبَنَّ), "forget" ("tansha" تَنسَىٰٓ ) which are all interpreted to refer to the process of "naskh":
Of the four verses within the Qur'an that "do" contain some form of the word "naskh" — verses Q.7:154, Q.45:29, Q.22:52, and Q.2:106 — in two cases the word has nothing to do with abrogation of divine revelation, but is used in the context of texts and scribal activity: 
The two verse that do involve abrogation are
Verses of abrogation.
 and are the two "verses of abrogation" contained in the Quran.
They establish the principle in Islam that an older divine revelation may be abrogated and substituted with another one, 
a principle that has been historically accepted and applied by vast majority of Islamic jurists of both the Quran and the Sunnah.
Only Q.2:106 uses a form of the word "naskh" (specifically "nanskh" meaning "we abrogate").
Although there "are no less than a dozen" readings/interpretations of verse Q.2:106 (according to Khaleel Mohammed citing John Burton), the "majority of exegetes" (scholars of the interpretation of the Quran), find 2:106 indicative of two varieties of abrogation (see below):
Two verse also suggest abrogation can refer to either these two meanings,
In addition, traditional non-religious Arabic sayings, poetry, etc. used to determine the meaning of Quranic terms also suggest abrogation means either suppression or supersession.
The verse Q.16:101 was employed by the founder of the Shafi'i school of Sunni Islamic jurisprudence — Imam Shafi'i — as proof that a Qur'anic verse can only be abrogated by another Qur'anic verse. (see below)
Orthodox/pro-naskh scholars (like Ali b. Muhammad b. Ibrahim 'Ala al-Din, known as al-Khazin) argues that Abrogation Verse 2:106 was revealed in response to allegations by unbelievers in Mecca "that Muhammad decides a ruling, then abrogates it!". However, according to Mohammed al-Ghazali this explanation cannot be true because the verse was revealed in Mecca where at the time "no such laws" were being abrogated. 
Another argument against the orthodox interpretation of the verse is that the word translated as "revelation" ("ayah") in the two Verses of Abrogation is ambiguous, and what is abrogated may be something other than a verse in the Quran. "Ayah" is more accurately translated (according to Khaleel Mohammed) as "sign" — as in a sign "sent down by God to guide humankind to Him" — revelation being only one kind of sign.
Satanic verses and abrogation.
The one other Quranic verse using "naskh" in sense of abrogation is .
This verse, is cited by historian and exegete Tabarī in connection with the incident of the so-called "Satanic Verses", 
Tabarī's interpretation ("Tafsīr"), states that God removed some of the early verses that the devil had cast into the Quran (making worship of other deities permissible) and replaced them in later verses.
It supports an interpretation of "naskh" as eradication ("izāla") so as not to be found in the written Quran ("Mus'haf") and thus made acceptable the idea of "naskh" as the nullification of a verse and ruling — "naskh al-hukm wa-'l-tilāwa" — without any (immediate) replacement.
Ibn Taymiyyah also identified "something that Satan has managed to insinuate into Revelation through Prophetic error" is naskh-ed by a divine verse, (which he calls "al-naw' al-ikharmin al-naskh").
But later exegetes such as Makkī insist that since the verse was insinuated by the Devil into the Prophet's recital, and not revealed by God, that verse Q.22:52 only provides for establishes the Islamic legitimacy of the concept of "naskh" for satanic not divine revelation. According to the current orthodox interpretation, the verses were actually a fabrication by Quraysh tribesmen and enemies of Muhammad. However "a number" of classical scholars like Musa b. 'Uqbah, Ibn Ishaq, Abu Ma'shar, al-Tabari, Ibn al-Mundhir, Ibn Abi Hatim, Ibn Mardawayh and Ibn Hajar al-'Asqalam have accepted the report about this episode as genuine" (according to Ahmad Hasan), based on the "isnad" (chain of transmitters of the report), other eminent classical scholars reject the report which if it were true would mean "that Satan could tamper with the Divine Revelation".
Sunnah/hadith.
Hadith/commentary abrogating Quranic verses.
Evidence for the abrogation (or not) of Quranic verses comes from collections of hadith, and tafsir.
Eight hadith in Sahih Bukhari mentions abrogation: 
Several hadith in Sahih Muslim mention abrogation of Quranic verses, including.
Three verses in Sunan Abu Dawood, two verses in Malik's "Muwatta" and two verses in Tafsir ibn Kathir mention abrogation.
As for abrogation of sunnah/hadith, there is no equivalent to the Quranic "Verses of abrogation" in the sunnah. No "generally accepted statements can be adduced from the sunnah to vindicate the application of the theory to Sunnah texts", according to John Burton.
However scholars state that hadith were abrogated just as the Quran was. "Kitab al-I'tibar" states that early Muslim Urwah ibn Zubayr declared, "I testify that my father told me that the Prophet would make a statement, then subsequently replace in with another statement, just as the Quran, in certain places, supersedes other parts." Abu al-‘Ala’ ibn al-Shikhkhir (d. 107/725),
a "Tabi‘i", (i.e. one of the generation of Muslims who followed the "Sahaba" -- the companions of Muhammad) is reported to have said much the same thing according to a Sahih Muslim hadith.
History.
In "general terms", the idea of a divine process whereby the decisions of a monotheist God can be superseded by His later decisions precedes "even the foundation of Islam itself," (according to John Burton), being found in "Epistle to the Hebrews" 8:13; 10:9 of the New Testament.
While Muhammad is reported to have abrogated parts of the sunnah by "explicit abrogation" (see below), there are no reports of him talking about abrogated verses in the Quran or explaining any theory of abrogation. Thus the classical theory of naskh "cannot go back to the Prophet". This is an argument against the theory according to its opponents — "it is inconceivable that the Prophet had left such an important problem to the discretion of the people ..."
There are, however, introductory stories in almost all classical "naskh" works about how (younger) companions of Muhammad — some of his "oldest and most determined supporters" revered by pious Muslims — emphasized the importance of belief in and knowledge of the theory of naskh.
Many recount an incident where a Kufan preacher is banned from expounding the Quran on account of his ignorance of the principles of "naskh" by an early "'ilmic" authority figure (usually Rashidun Caliph 'Alī, but sometimes also Ibn 'Abbās, cousin of Muhammad and hadith narrator).
In one report Ali told a judge who had no knowledge of nasikh that he was "deluded and misleading others", in another he evicted a preacher from a mosque for being ignorant of the science of abrogation. Umar is reported to have told Muslims that despite the fact that Ubay ibn Ka'b was "the best Quranic expert among us ... we ignore some of what" he says because he disregarded abrogation and told others he refused to "abandon anything I heard from the Messenger of Allah".
Another set of Hadith emphasize how those who speak publicly on "fiqh" (Islamic law) without expert knowledge in naskh not only endanger their own immortal souls but also the souls of those who listening to them.
Some (John Burton) have questioned the authenticity of these hadith, finding them suspiciously convenient for proponents of naskh and especially for experts in the field. (Not only do they provide validity for the theory from "the mouths of men believed to have known the Prophet's mind best", but the reports specifically call for judicial or religious offices in the community to be occupied by those trained in "this indispensable knowledge".)
However even if these reports were later fabrications and the rules of naskh were not directly passed down from Muhammad to the Salaf Muslims, it is known that the "idea" that some Qur'anic verses were abrogated can be found towards the end of the first century of Islam, and the development of "theories" of naskh can be dated "with certainty" to the time of Imam Shafi'i (d.204 AH).
The early schools of law that were in existence towards the end of the first century of Islam included the idea of abrogation in the Qur'anic verses. Ibrahim al-Nakha'i (d.96 AH/714) is reported to have said that the part of verse Q.5:106 — which allows a non-Muslim to bear witness to the bequest of a Muslim during a journey if the Muslim is on their death bed — was abrogated to require the witness to be a Muslim.
The principle of abrogation (without its "naskh" terminology) makes an early appearance in the "Muwatta"' of Mālik (d.179 AH/795 ) according to John Burton and Ahmad Hasan. At one point Malik notes that "his teacher Zuhrī had told him that the Muslims had adopted as standard the latest of all the Prophet's reported actions" when there is a conflict. In another chapter Mālik states that of the two conflicting Qur'an rulings, "one had replaced the other". Elsewhere, Mālik "rejects the notion that a ruling remains valid despite the withdrawal" of the (supposed) Qur'an verse the ruling is based on.
However, according to Abdul-Rahim, "the earliest extant materials ever written" on the "tafsir" genre, naskh al-Qur’an came earlier than Malik. The two works — "Kitab al-Nasikh wa al-Mansukh fi Kitab Allah Ta‘ala" by Qatadah ibn Di‘amah al-Sadusi (d. 117/735) and "Kitab al-Nasikh wa al-Mansukh" by Muhammad ibn Muslim ibn Shihab al-Zuhri (d. 124/742). — begin "immediately to point to the abrogated in the Qur’an" feeling no need to elucidate what naskh is. According to Abdul-Rahim, the fact that these and other early works followed this practice indicates a "widespread understanding of naskh" in the Muslim world at that time.
"Naskh" meaning evolved as early applications of the concept were abandoned (like other technical terms within Islamic exegesis — such as "asbāb al-nuzūl", the historical context in which Quranic verses were revealed). In early works of "tafsīr" (before about 150 AH), "Naskh" was used to refer to a ruling that narrowed rather than replaced an earlier one ("nasakha min [al-āya]" — "an exception is provided to [the verse]"). This usage was later reformulated by Shāfi'ī as "takhsīs" (specification/exception).
The "elaboration of the theories" of naskh can be dated with certainty to the last half of the second century of Islam, when Imam Shafi'i (d.204 AH/820), in his work "Risāla", (and in the somewhat later "Ikhtilāf al-Hadīth"") worked to resolve the "apparent discrepancies between certain Qur'ānic verses and others; between certain "hadith" and others; and, most serious of all, between certain Qur'ānic verses and certain "hadīths"", according to John Burton. Ibrahim al-Nakha'i (d. 96/714) is reported to have said that verse Q.5:106 was abrogated
"Naskh" as "a technical term meaning 'abrogation'" was used "early on in exegesis, for example, in Muqātil's [d. 149-150] "Khams mi'a āya" and his "tafsīr". "'Ilm al-Nasikh wa'l-Mansukh" (Knowledge of the Abrogating and Abrogated) became one of the Islamic sciences.
John Burton argues, naskh become more important following the establishment of the principle of As-Shafi’i that hadith of Muhammad overruled all other reports from Companions or others on the same subject. This doctrine led to the growth in hadith attributed to the Prophet. Since “far too many" of these hadith "were mutually contradictory”—some contradicting the Quran -- “their use might court the risk” of failing to follow divine law (the view of some of the Mu’tazila of the era). For proponents of the As-Shafi'i doctrine a practical problem was the contradictions would lead to an abandonment of basing Islamic law on prophetic hadith.
At least by the eleventh century the classical concept of naskh of the Quran and Sunnah was widely accepted enough for one scholar — Ibn Hilal al-Nahwi — to assert that "whoever says" that there is no abrogation in Islam "is not a believer, but rather a "kafir", denying that with which Muhammad came. He must renounce his position or be killed".
A "celebrated icon" of deniers and rejecters of naskh was the fourth-century Hijri scholar, Abu Muslim al-Isfahani, who was very much in the minority and whose work on naskh "Jami‘al-Ta’wil" (al-Amidi, al-Ihkam, v.3, 115), has been lost to history.
But "concentrated criticism of the abrogation concept only started in the latter part" of the nineteenth century, according to Khaleel Mohammad. According to Karel Steenbrink, "most" of the modernist or reformist scholars of that era (Muhammad Abduh, Sir Sayyid Ahmad Khan, and Rashid Rida), considered the theory of abrogation of the Quran invalid. Muhammad al-Ghazali, writing in 1992, stated 
"the position taken by all the modern scholars whom I have met, or listened to, or whose works I have read, is contrary to the understanding of naskh that became so widespread among the later exegetes, namely that there exists naskh (if accepted) as meaning the abrogation of verses of the Qur'an."
Two lesser known scholars who wrote work and spoke against naskh of Islamic revelation in more depth in the 20th century were Muhammad Amin (an Azhar graduate, active at the beginning of the 20th century), and 'Abd al-Muta'al al-Jabri (who wrote his Master's thesis—entitled "Naskh As I Understand It In The Islamic Shari'ah"—at the University of Cairo in 1949).
Need and scope.
Dealing with apparent contradictions.
Islam teaches that the Quran was revealed to Muhammad over 23 years (609-632 CE) until the year of his death. The customs and practices of Muhammad over this same period are known as the Sunnah, and reports of them are known as ahadith. From early in Islam's history, some scholars thought that contradictory commands existed in the Quran, among hadith of the Sunnah, as well as between verses of the Quran and the hadith.
Since Islam calls on humanity to obey the Quran and imitate the behavior of the prophet, and also because "a defining claim of Sunni Islam" is that no two authentic hadith could contradict each other or the Quran, (and because some verses in the Quran at least seemed to contradict each other) scholars worked to resolve these apparent contradictions in the verses that give regulations to Muslims.
This became especially important, (as mentioned above), after the principle of fiqh was established that in forming Islamic law, hadith attributed to Muhammad overruled those attributed to all other early Muslims on the same issue. This led to the growth in the number of these hadith and contradictions between them, created a danger to their legitimacy as the basis of sharia law.
While hadith tell of rules of naskh being passed down directly from Muhammad's closest Companions (sahabah) and future Muslim leaders — others believe it more likely ideas about naskh originated later. Ahman Hasan speculates that the idea of the abrogation of certain Qur'anic verses "emerged" early in the history of Islam when commentators and the jurisconsults seeking to reconcile the "apparently contradictory verses", looked to the Quranic verses such as Q.16:110 — "... We put a revelation in place of (another) revelation ..." — to develop a theory that some later verses replaced the commands of earlier ones.
John Burton argues that naskh was first employed by Islamic scholars ("usulis") in the second century of Islam working to develop principles ("usul al-fiqh") for the Islamic law (fiqh) and seeking to explain why some fiqh rulings were not founded on Quranic/Sunnah revelation. By this time the Islamic empire spanned three continents and fiqh had been established in the different regions but usulis found rulings in certain verses of the Quran and parts of the Sunnah had been ignored in their formulation. To explain this, Burton argues, they developed the concept of naskh to declare that the verses/parts had been abrogated.
In theory, "naskh" formed part of a hierarchy of techniques used by scholars of Islamic law working with hadith. Scholars first strove to “harmonize” hadith, (i.e. to make them fit together by reinterpreting them). If that failed they would look for signs of abrogation (that one saying/doing/inaction by Muhammad was earlier than the other and had been replaced by the later saying/doing/inaction). 
If there was no opportunity for abrogation, they would check the "isnad"—chains of transmission of the hadith—to see if the transmission of one hadith was superior to another. Finally, if they found no difference in the "isnad", they would approve the hadith they found "closest to the overall message of the Quran and Sunnah".
But according to scholars such as David S. Powers and John Burton, while the doctrine of abrogation may have cleared up contradictions, it "poses a difficult theological problem" because it seems to suggest God was changing His mind, or has realized something He was unaware of when revealing the original verse. For an eternally all-knowing deity this was theologically impossible and logically absurd — in fact an act of "unbelief" in Islam itself. 
Also foreclosing on the possibility of any improvisation of Quranic verses was the belief of Sunni scholars that the Quran was not written/spoken during the course of its revelation, in fact not even created/written by God, but is as ageless as God himself, "uncreated", an "attribute" of God (like being all-powerful, beneficent, merciful, etc.), its original copy being the "mother of the book" — "umm al-kitab" — kept in the presence of God (Q.13:39; Q.43:4), the earthly Quran being only a copy of it. (The Mutazilah argued that the Qur'an could not be both eternal and subject to abrogation, with a new verse abrogating an earlier one.)
Skeptics such as Ali Dashti found the naskh process suspiciously similar to the human process of "revising ... past decisions or plans" after "learning from experience and recognising mistakes".
When the Quran defends abrogation/naskh against those who scoffed at it ("Do not you know that Allah over every thing?" Q.2:106; "they say, "Thou art but a forger" ... Allah knows best what He reveals" Q.16:101), Dashti asks if the "scoffers" were suspicious "precisely because God is capable of everything", and so would have no need to abrogate a verse after revealing it.
Roslan Abdul-Rahim points out that after a verse was revealed criticizing Muslim slackers and urging Muslims to fight jihad, a blind Muslim (‘Abd Allah ibn Umm Maktum) protested to Muhammad that his eyesight prevented him from fighting. "Almost instantaneously" another verse was sent down amending the first with the qualifier "except the disabled".
Rationale.
At least in part in answer to these criticisms, some explanations and defenses have been offered for the theory of abrogation — principally that the revising of commands by God to his creatures is all done according to a plan.:
Alcohol.
The "classical" and oft cited example of how naskh was used in stages to guide a major change in the behavior of the faithful was the banning of alcohol, implemented in three verses. It has been described as an act of wisdom, needed because an abrupt total ban would have been too harsh and impractical. "Arab society in the beginning was not ready to abandon drinking alcohol. They needed to strengthen their faith in order to overcome their desire to drink."
The first verse gently discouraged Muslims from drinking alcohol:
The second prohibited Muslims from being drunk during one kind of activity—praying salat:
And finally, once Muslim were "ready for it", alcohol (along with gambling) was totally prohibited:
Ratio of enemy warriors to Muslims.
Two verses Imam Al-Shafi'i cites as "the clearest evidence" for naskh concern the number of enemies each Muslim warrior is expected to vanquish. (Unlike with those concerning alcohol, the abrogating verse is more lenient not more strict.)
<BR>A verse calling for overcoming ten unbelievers
... is abrogated by one reducing the number of enemy Muslims are expected to fight to only two:
Another example of this "takhfīf" (lightening) is lifting the burden of lengthy nocturnal prayers in that had been required by .
The Sword verse(s).
A verse(s) of major importance in Muslim-non-Muslim relations is the "Sword verse" (as, to a lesser extent, are similar verses such as ).
Among "medieval exegetes and jurists" there was "a broad consensus that and abrogated "all the other statements" in the Quran "on the issue of waging war".
In modern times, the sword verse has been used by extremist groups and individuals to justify their killing of non-Muslims civilians, according to Lohay Fatoohi (although some dispute this),
and Mahfuh Halimi argues extremist advocates of violence maintain the verse of the sword Q.9:5 abrogates "more than a hundred" verses of the Quran advising or advocating "peace, coexistence, patience, tolerance, and forgiveness as the basis for relations between Muslims and non-Muslims." Critics have called this a case of passages called for killing abrogating ones calling for tolerance. and a classic example of determining the validity of a verse by determining when it was revealed.
Some verses counseling patience, forbearance, etc., said to be abogated by 9:5 (according to Fatoohi) include:
Similarly verse Q.9:29 is considered by Nahhās "to have abrogated virtually all verses calling for patience or forgiveness toward the People of the Book" (according to Reuven Firestone). (The verse abrogates more early verses of the Quran than any other according to some Muslim Islamic scholars, while others have concluded it does not abrogate any verses.
Length of the period ("`iddah") widows must wait before remarrying.
This abrogation—mentioned above as an example of "total abrogation" (aka "naskh kulli")—has been called a "'classic' instance" of the "'classic' mode" of naskh by Usulis (i.e. students/scholars of the principles of fiqh) that 'proves' ""the fact" of Naskh". It (is thought to have) shortened the "`iddah", i.e. the waiting period for widows (also divorcees, but these verses refer only to widows) before re-marriage, from one year ...
... to four months and ten days: 
But Q.2:240 makes no mention of a waiting period before marriage, but only financial provisions ("maintenance and residence", aka "matāʿ") for widows. This "did" conflict with "the details of the rules to govern inheritances laboriously worked out in the fiqh", (according to non-Muslim critic and scholar John Burton). Burton argues that protecting established fiqh rulings from the contradiction of Quranic verses such as Q.2:240 (and not addressing conflicts between different lines of revelation) was what motivated the usulis who developed the theory of naskh.
Questions raised.
In reply to the rationale of gradual introduction of the ban on alcohol, some (Farooq Ibrahim ) have noted that while hadith often explain events that the Quran refers to cryptically, there is no explanation or mention of a strategy of gradual banning of alcohol consumption found in any Sahih hadith. Nor was a gradual process used in other Islamic prohibitions. The worship of multiple gods, and of having intercessors before God were both banned with no evident concern over whether they were too harsh or impractical.
Burton suggests that the idea that naskh can be explained as "takhfīf" (lightening) is of limited usefulness because it is applied to both naskh that make things easier for Muslims in the temporal world — like no longer requiring lengthy nocturnal prayers or lowering the number of enemies each Muslim warrior is expected to vanquish; and abrogation that makes things more difficult — for example, the extension of the ritual fast from a few days () to the entire month of Ramadan (). Here the changes are claimed to be lightening because they will help Muslims attain a greater reward in the Hereafter. Still other abrogation — such as the switching of the "qibla" — would seem to have no effect on the difficulty or ease for Muslims of either temporal life or the afterlife.
The doctrine (expressed here by Louay Fatoohi) that God "knows the temporariness or permanence of any ruling from the time He issues it",
seems hard to square with two verses mentioned above; where God promises that Muslim warriors will overcome ten times that number of unbelievers (Q.8:65), before revealing an abrogating verse — "Now God has alleviated your burden, knowing that there is weakness in you," and lowering the number of unbelievers promised to be overcome to only double the number of Muslims (Q.8:66), suggesting that God abrogates after learning of an area of Muslims' weakness.
A question raised over how aspects of the Quran's message and the Prophet's teachings needed to change over the course of Muhammad's mission as times/circumstances changed, was why the need for change stopped with the death of Muhammad. Muhammad Abduh (reputedly) asks why naskh was employed during the 23 years of the Quran's revelation, but could not be employed over the next 1400+ years when social & life changes were far greater.
Limits of application.
Scholars have proposed some limits on the application of abrogation.
Naskh concerns itself with only revelations pertaining to positive laws — commandments ("amr") or prohibitions ("nahy").) In Tabarī's words:
Naskh is applied almost exclusively to the Qur'an and the Sunnah. According to Mohammad Hashim Kamali and Hafiz Muhammad Azeem its application to "Ijma`" and "Qiyas" — secondary sources of Sunni Islamic law unlike the Qur'an and the Sunnah not divinely revealed — "has been generally overruled", as abrogation "is not relevant" to "Ijma" (the consensus or agreement of Muslim scholars on a religious issue), and the theory of naskh "has no place" in "Qiyas" (the process of deductive analogy in Islamic scripture in order to apply a known injunction ("nass") to a new circumstance and create a new injunction). Islamic jurists cannot abrogate, it is confined to the lifetime of the Prophet in the Qur'an and Sunnah.
In addition, subjects of Islam that Naskh does not apply to include:
If these conditions are met, there are several more that must be satisfied concerning the text to be abrogated and the text abrogating:
According to scholar John Burton three "elements" are necessary "in any one alleged instance of naskh", namely:
Scholar Recep Dogan, gives "types of evidence" allowed for "naskh". (These are also three in number, but only one — chronology — is the same as Burton's "necessary elements"):
Since an abrogating verse must have been revealed after the verse it abrogates, the validity of abrogation requires a knowledge of the chronology of the primary sources.
This has historically been a difficult task because the verses in the Qur'an are not arranged by chronology but rather by size of chapters, and even within a chapter, the verses are non-chronologically arranged, so that the context of each revelation is not ascertainable from verses near a verse, or the sequential verse number. 
Verses Q.2:190, Q.2:191 and Q.2:192, for example, were revealed to Muhammad six years after the verse Q.2:193. 
Thus chronology depends on "the agreement of scholars" ("ijma") and on "Tafsir" reports or the recollection of Hadith transmitters to explain which verse or prophetic statement was revealed before another.
Types/varieties.
Implicit and explicit naskh.
Most cases of naskh are "implicit" ("dimni") — i.e. as noted above they depend on "the agreement of scholars" ("ijma") to determine if a verse was abrogated. However, a few revelations involve "explicit" ("sarih") naskh, specifically mentioning some earlier command to be abrogated and replaced with another — though none of them use any form of the word "naskh".
Total and partial naskh.
Abrogation may be divided into two more types: total abrogation and partial abrogation:
In the case of "total abrogation" (or "naskh kulli"), all of the specific statement within the Quran or hadith that the ruling is based on (the "nass") is abrogated by another, and a new ruling ("hukm") is enacted to replace the entire old ruling. An example is found in two Qur'anic verses on the waiting period ("`iddah") of widows before remarriage.
<BR>Al-Baqarah 240 has been interpreted to prescribe a waiting period of one year:
But another verse shortened the waiting period to four months and ten days:
In the case of "partial abrogation" ("naskh juzi"), one verse is only partially abrogated by another. The part not abrogated remains operative. An example of this is the Qur'anic verse on slanderous accusations of adultery against women (known as "qadhf").
The "ayah of qadhf" — An-Nur 4 — establishes a general rule that anyone who accuses chaste women of adultery ("zina") must produce four witnesses for proof:
The "ayah of imprecation" ("li'an") — an-Nur 6 — replaces the four witnesses requirement, but only for one kind of person — the husband of the alleged adulteress. It allowing him to pursue charges of "zina" against his wife provided he takes four different oaths to tell the truth and invoked the curse of God upon himself if he is telling a lie. This partially repeals Ayah Q.24:4.
"Takhsees" ['specification', also spelled "takhsis"] and "istithnā" (exception) resemble "partial naskh" described above. Like partial naskh, "takhsees" qualifies a general ruling ["'aam"], so that it only applies in certain cases.
Examples include 
"Takhees" is sometimes called another name for partial naskh. However (according to Deen Communication Limited), "Takhsees" differs from naskh in that
Naskh of ruling, Naskh of verse, or both.
Another set of types of naskh are those divided by what is abrogated — ruling, text, or both. (John Burton calls these the three "modes" of the theory of "naskh".)
But there are two other less accepted (and much less common) varieties of naskh that "do" abrogate text, i.e. involve revealed verses that were omitted from the text of the "Mus'haf"(and thus creates a distinction between the Qur'an as temporally contingent document-i.e. the "mus'haf"- and the Qur'an as the unity of all revelation ever sent down to Muhammed).
According to Ahmad Hassan, these last two types of abrogation of wording/scripture are "not supported by conclusive evidence". According to John Burton, one of the two types -- #2, abrogation of the wording but not the ruling—is acknowledged "only by a minority of scholars".
1. "naskh al-hukm dūna al-tilāwa"
Examples of verses in the written Quran ("Mus'haf") that no longer provide a basis for a regulation/ruling (hukm) include most cases of abrogation mentioned above (the two cases of explicit abrogation that involved hadith being the exceptions).
Some have asked why the verses were not edited out of the "mus'haf" when it was compiled. Doesn't retaining the verse run the risk of causing confusion to those inadvertently following the repealed rule? A number of rationales have been given for the practice. Tampering/doctoring with sacred texts has been rejected since medieval times — according to Liaquat Ali Khan. Al-Suyuti gives two reasons for their not being purged: 
1) it was meritorious to recite the Word of Allah, whether or not the verses had been abrogated;
...the Qur'ān was revealed so that its rulings might be known and their implementation rewarded; but... the Qur'ān is also recited with reverence, since it is the word of God, for whose recitation the pious Muslim is likewise rewarded. Further, to leave the wording, following the abrogation of the ruling was to provide for men a constant reminder of the compassion and mercy shown by their gracious Lord ["ar-Rahman"] Who had lightened the burden of some his previous requirements. 
2) the verses were "a reminder of God's mercy", since abrogation "was generally directed to making things easier", Muslim could read them and see how their burden had been eased by God's abrogation.
Another question raised is whether abrogating rulings ("al-hukm") but not Quranic wording ("al-tilawa") contradicts the verse of abrogation Q.2:106 which states "any "ayah" We cause to be superseded or forgotten, We replace with something better or similar", and not "any "hukm" We cause to be superseded or forgotten ..." The Arabic word "Ayah", is the word used in the Quran for verses in that book, although it is also used for other of God's "signs". If God intended for sharia rulings and not wording to be abrogated why wouldn't verse Q.2:106 say so?
Tafsir scholar Tabarī ingeniously explains this problem away by noting that the faithful believe that no one part of the Quran can be "superior" to any other part (because the Qur'an was composed by the divine author and is "Mu'jaz", or so miraculous it is impossible to imitate). However 2:106 talks of God replacing "ayah" "with something better or similar". Since all verses of the Quran are all equally wondrous, ayah in this context cannot be referring to the words of the Quran. The principle of "mu'jaz", however, does not carry over to shari'a law whose "wording" is not divine (those its substance is) and whose quality may vary in excellence. Thus, by process of elimination, John Burton explains, "the only other thing it ["ayah" in Q.2:106] can refer to is the ruling derived from the verse," i.e. "the rulings of the shari'a", "hukm".
Still another issue was how ayah could be forgotten ("cause to be forgotten") when a prophet like Muhammad was meant to be protected from flaws like forgetting. This was explained by modifying the definition of "cause to be forgotten" ('aw nasaha) to "defer" or "leave".
2. "naskh al-tilāwa dūna al-hukm"
This form of naskh — abrogation of the wording ("al-tilāwa") of some part of the Quran but not the ruling ("al-hukm") based on that part — is acknowledged "only by a minority of scholars".
The traditional evidence offered for it is the lack of verses for "rajm" [stoning adulterers], and "rada" [kinship from breastfeeding] in the Quran, notwithstanding the fact that both are generally accepted parts of traditional Islamic law. In the first case, a punishment of stoning to death (lapidation) for adultery is found in the Islamic law of the founders of all four surviving schools of Sunni fiqh ("madhab") and by the majority of scholars of fiqh, but the penalty prescribed for adultery in the "mus'haf" is flogging (in Q.24:2).
An explanation for this is that a "stoning verse" ("āyat al-rajm") was abrogated but not the ruling. (Another is that hadith calling for the stoning punishment abrogate the flogging punishment in the Quran, see below.) Muhammad's favorite wife Ā'isha , claims that there was a stoning verse in Quran that was lost, as do other hadith.
However, evidence for the existence of this verse has been criticized as weak, the hadith unreliable, and followers of Maliki and Hanafi fiqh believe evidence for stoning being the proper Islamic punishment comes not from an alleged Quranic verse but from reports of Muhammad calling for execution of adulterers by stoning found in collections of sound ("sahih") hadith — meaning that the hadith on stoning abrogate the flogging verse in the Quran. Ahmad Hasan agrees that the punishment of "rajm" is based on the Sunnah of the prophet and argues that the wording of the Verse of Rajm found in hadith "appears to be manifestly of a different style than that of the Quranic verses". He also believes that 'Umar's explanation for not including it in the "mus'haf" does not make sense.
Sahih al-Bukhari 6829, Book 86, Hadith 56, Hadith 816 states:
`Umar said, "I am afraid that after a long time has passed, people may say, "We do not find the Verses of the Rajam (stoning to death) in the Holy Book," and consequently they may go astray by leaving an obligation that Allah has revealed. Lo! I confirm that the penalty of Rajam be inflicted on him who commits illegal sexual intercourse, ...
Roslan Abdul-Rahim argues "the cases of "rajm" [stoning], and "rada" [kinship from breastfeeding] do not support this form of abrogation: 
The trouble with this understanding however is, Q.2:106, the report of Ubayy questioning the Prophet, and the exchange between ‘Abd Allah ibn Zubayr with ‘Uthman ibn ‘Affan, all suggest that naskh is not synonymous with forgetfulness, disappearance of revelations or the exclusion of revelatory texts from the Qur’an.
This form of "naskh" also poses the question of why a verse important enough to be the basis of immutable "hukm" (ruling) dealing with life and death would disappear from the written Quran ("mus'haf"), and what scripture allows it.
Another report used to support "naskh al-tilāwa dūna al-hukm" — where Aisha states that a Quranic verse requiring only five suckling of a child to establish foster-parentship was abrogated but which later became the basis of a certain rule in Islamic law — is argued against by Ahmad Hasan on the grounds that rule was rejected by "the ancient schools of [Islamic] law". Hasan also argues against the report that some surahs ("muawwadhatdn") were not included in the "mus'haf" saying that "certain companions" heard Muhammad reciting a "qunut" or "du'a" prayer and thought it was part of the Qur'an.)
In support of this form of naskh was Al-Shafi'i, who disagreed with Maliki and Hanafi and maintained that the Sunnah cannot abrogate the Quran and the Quran cannot abrogate the Sunnah. (This left "naskh al-tilāwa dūna al-hukm" as the way to explain the punishment of stoning.) While Shāfi'ī never postulated the existence of a "stoning verse", he did acknowledge the probability of "abrogation of wording but not ruling", as well as acknowledging Aisha's claim that there was a stoning verse in Quran, which had been lost.
3. "naskh al-hukm wa-'l-tilāwa"
Examples of abrogation of both ruling and wording — where a ruling is voided and its text omitted from the "mus'haf" so that the only evidence that it ever existed is in hadith — include the alleged "Satanic Verses" mentioned above, and a (much less controversial) report on how a wet nurse may become a foster parent, (specifically on how many times a wet nurse may breast-feed someone's child before that child is forbidden to marry any of the wet nurse's natural children. A hadith attributed to Aisha states that "among the things that were revealed of the Qur’an was that ten definite breastfeedings make a person a mahram". That verse was then "abrogated and replaced with five definite breastfeedings, and the Messenger of Allah ... passed away when this was among the things that were still recited of the Qur’an." Narrated by Muslim, 1452.)
Liaquat Ali Khan states that "very few Muslim jurists concede that any portion of the Quran has been removed" through this mode of abrogation. However, Wahhabi scholar Muhammad Saalih al-Munajjid, in describing this mode of "Naskh", quotes two other scholars (Muhammad ‘Abd al-‘Azeem az-Zarqaani and Ibn ‘Atiyyah) who subscribe to its use. And John Burton writes that this mode is generally acknowledged, in part due to the many alleged instances of revelation being erased:
As to how both ruling and wording were abrogated, supporters point to divine intervention into the memories of Muhammad and his companions causing them to forget a revelation,
"Qur'ān-forgetting is clearly adumbrated in the Qur'ān", according to Burton, and couple of verses of the Quran talk of God taking away a revelation or causing it to be forgotten: 
A number of hadith also attest to the phenomenon of forgetting revelation — some describing the forgetting as "a natural failure" of Muhammad's or companions memory, and others as a "miraculous intervention" by God. One claims that entire suras which the Muslims had previously recited, would be discovered one morning to have been completely erased from memory.
The question of whether not just some but "all" abrogated verses ("mansukh") were deleted from the "mushaf", (meaning that contrary to scholarly consensus, there is no "classic" mode of naskh, no #1. "naskh al-hukm dūna al-tilāwa", because nothing included in the "mushaf" has been abrogated, no "mansukh" is found there) has been raised by Roslan Abdul-Rahim. A Bukhari hadith about second caliph 'Umar ignoring Ubai recitations including "revelations that had allegedly been abrogated", indicates early Muslims ignored verses that had been abrogated, so that these verses would not have found their way into the "Mushaf".
However, another Bukhari hadith indicates the opposite, according to Roslan Abdul-Rahim, reporting that the compiler of the "mushaf" himself — the third calif "'Uthman ibn Affan" — declared that he would not "shift [any verse] from its place", indicating no verses would have been excluded from the "Mushaf", even if abrogated.
In addition, according to Abdul-Rahim, verse Q.2:106 and the report of Ubai questioning the Prophet, also suggest that naskh is not synonymous with forgetfulness of revelation. (‘Abd al-Rahman b. Abza reports that on one occasion, the scribe Ubayy -- noticing that Muhammad had skipped a previously recited verse -- "asked if the Prophet had forgotten a verse or that it had been abrogated ...")
Abrogation of Quran and Sunnah by one another.
Yet another way of classifying naskh is by what "kind of revelation" is abrogated and what kind is abrogating. 
Some scholars (a minority) believe that different types of revelation cannot abrogate each other — a part of the Sunnah can never abrogate a verse of the Quran and vice versa.
Distinguishing between which of the two kinds of revelations are involved in abrogating and in being abrogated creates four variations of "naskh" in this classification: 
Regarding variety #3, (Sunnah abrogating the Quran), a consensus of scholars believe that Quranic verse 2:180 — the "ayah of bequest" in al-Baqarah:
...has been abrogated by a hadith included in Sunan Abu Dawood collection. 
An example of variety #4, (abrogation of part of the Sunnah by a Qur'anic verse) is found above as an example of Explicit Naskh above — namely what the "qiblah" (direction facing during salah prayer) should be. This direction was originally Jerusalem/Quds according to hadith included in the collection Sahih al-Bukhari (41)
... was abrogated by Ayah 144 of Surah al-Baqarah:
Arguments on abrogation between sources.
While abrogation by the same type of revelation — i.e. varieties #1 and #2 — are accepted by all scholars (i.e. all who support the orthodox theory of abrogation), abrogation between types of revelation — #3 and #4 — are not.
The scope of Naskh doctrine between sources has been one of the major differences between the Shafi'i and Hanafi fiqhs, with Shafi'i sect of jurisprudence forbidding abrogation by the Sunnah of the Qur'ān, while Hanafi sect allowing abrogation by the Sunnah of the Qur'ān.
Other descriptions of the breakdown in differences are that (according to Hafiz Muhammad Azeem), Imam Al-Shafi‘i, Imam Ahmad ibn Hanbal, and the majority of the Muʿtazila, hold that a ruling in the Sunnah can not be abrogated by a ruling in the Quran, and vice versa, but later scholars accepted that they can be.
The Maliki, Shafi'i and Hanbali schools of Sunni Islam maintained that a Sunnah practice from a Hadith can never abrogate a Quranic verse, (according to Yusuf Suiçmez). In contrast, the Hanafi fiqh of Sunni Islam, from the days of Abu Hanifa, along with his disciples such as Abu Yusuf, believe that Sunnah can abrogate a Quranic verse.
Al-Shafi‘i bases his opposition on Q.16:101 and Q.10:15, according to Hafiz Muhammad Azeem:
For Al-Shāfi'ī "I merely follow what is being revealed to me" in meant to that "the sunnah cannot abrogate the Book" but only "follow what it laid down in" it, (according to Yusuf Suiçmez).
Al-Shafi‘i adduces Q.2:106 as "categorically" allowing abrogation of the Quran only by the Quran, according to Ahmad Hasan, and argues that the Quran cannot abrogate the Sunnah because if this were allowed a "host of rules framed by the Prophet would be cancelled". (Stoning of adulterers would be replaced by flogging, etc.) According to another scholar, (John Burton), Al-Shafi'i argues that it is not possible for the Quran to abrogate the Sunnah because "were a Sunnah to be replaced, for example by a Quran revelation, a fresh Sunnah would accompany this revelation, in order to demonstrate that the Prophet's later Sunnah had superseded his earlier Sunnah ...", i.e. having spoken a revelation contradicting what he said or did to his companions, God's messenger would correct what he spoke or did.
"Shāfi'ī set his face decidedly against any acceptance of the idea then current that in all such cases the Qur'ān had abrogated the Sunnah, or the Sunnah the Qur'ān," Burton writes. Shafi'i insisted that "... any verbal discrepancies between the Qur'ān and the reported sayings or reports of the practices of Muhammed — the Sunnah of the Prophet" were illusions that "could always be removed on the basis of a satisfactory understanding of the mechanism of revelation and the function of the prophet-figure".
Shafi'i's stance was a reaction to larger developments within Islamic jurisprudence, particularly the reformulation of the "fiqh" away from early foreign or regional influences and toward more eminently Islamic bases such as the Quran. This assertion of Qur'anic primacy was accompanied by calls for an abandonment of the Sunnah. Shāfi'ī's insistence upon the impossibility of contradiction between Sunnah and Qur'an can thus be seen as one component in this larger effort of rescuing the Sunnah:
According to Burton, another argument against this "crossover" of types of revelation in abrogation revolved around concern that unbelievers would use it to argue against the validity of Islam.
If the Sunnah "naskhed" the Quran, unbelievers would be able to say that "Muhammad was saying or doing the opposite of what he alleged was being revealed to him by God"; while if the Quran abrogated the Sunnah they could claim that "God was belying the man who claimed to be His Prophet". 
One reply to these arguments against crossover of kinds of revelation in abrogation was that the Sunnah — like the Quran — "had also been revealed to Muhammad", and if the Sunnah abrogated the Quran or vice versa, it was "merely" a matter of "one element of revelation" replacing "another". The argument that the Sunnah/Muhammad's actions were of divine origin/revelation was based on Quranic verse 
(The opposite point of view — that the Sunnah could not naskh the Quran was based on:) 
While for Al-Shāfi'ī, "I merely follow what is being revealed to me" in meant to that "the sunnah cannot abrogate the Book" but only "follow what it laid down in" it, the Hanafi jurists used that verse to justify their opinion that abrogation of the Qur’an by the life actions of Muhammad (Sunnah) was based solely on his Divine inspiration, that when he acted or said anything, any abrogation implicit through his action, of the earlier Qur’anic ruling was from Allah alone. Hanafi school stated, adds Suicmez, that to accept that "a Sunnah can abrogate the Qur’an entails honoring of Muhammad".
Another argument for allowing abrogation between the Quran and the Sunnah and against the Al-Shafi‘i position that Burton believes had no effective counter-argument was the issue of the penalty for adultery in Islamic law. As mentioned above this was stoning death (something widely supported by the Sunni schools of fiqh including the school of Al-Shafi'i, but this punishment was found only in the Sunnah; in the Quran, verse Q.24:2 clearly called for 100 strokes of the lash — not execution — as a penalty for adultery. The only explanation for this was that this point of Islamic law was based on abrogation of the Quran by the Sunnah.
Abrogation of Jewish and Christian texts.
One type of abrogation over which there is little dispute among Muslims is "external naskh", the abrogation of earlier Jewish and Christian religious laws handed down in the Tanakh and New Testament by Islamic revelation. 
John Burton states that it "cannot be doubted" that Muhammad believed this. 
A wide variety of Islamic scholars — Syed Ahmad Khan, Muhammad Al-Munajjid, Hafiz Muhammad Azeem — also states that "naskh" applies "between religions", i.e. that the Qur'an has cancelled "the laws enunciated in the earlier Divine Scriptures like the Old and the New Testaments".
Quantity.
There has never been a consensus among Islamic jurists about which and how many Quranic passages (or Sunnah in the Hadiths) naskh affects.
Neal Robinson sees scholars estimation of the number of abrogating verses waxing and then waning over the centuries. 
Az-Zuhri (d.742), an early authority in the subject, held that 42 ayas had been abrogated. After his time, the number steadily increased until an upper limit was reached in the eleventh century, with Ibn Salama claiming that there were 238 abrogated ayas, and al-Farisi claiming that there were 248. In subsequent generations, a reaction set in: Egyptian polymath al-Suyuti (d.1505) claimed that there were only 20, and Shah Wali Allah of Delhi (d.1762) whittled the number down to 5.
David S. Power gives a higher peak number of abrogated verses of over 550 at around the 10th century CE.
According to John Burton, the number of verses alleged to have been expunged from the "mus'haf" (internal naskh within the Quran or " naskh al-hukm wa-'l-tilāwa") was higher—564 verses or almost 1/10 of the total content of the "mus'haf".
As mentioned above, one reason for the difference in tallies of abrogated verses comes from a confusion over the difference between "naskh" (abrogation) and "takhsees" (clarification). 
Yasir Qadhi declares that calling "takhsees" verses "naskh" inflated the number of naskh verses. Similarly, Ibn Al-Qayyim and Abu Amina Elias argue that what early Muslims called abrogating is now considered interpretation:
 The general meaning of the righteous predecessors when using the words ‘abrogating’ and ‘abrogated’ is sometimes the complete removal of the previous ruling – and this is the technical term of the latter generations – or sometimes the removal of the general, absolute, and outward meaning, whether by specification, restriction, interpreting an absolute as limited, or by explanation and clarification. Even they would refer to is as exceptional and conditional.
Scholarly questions and alternatives.
Questions/criticism.
Muslim.
While belief in the theory of "naskh" of Islamic revelation is part of Sunni Muslim orthodoxy, there are more than a few scholars who do not accept it, including most twentieth century modernist reformist scholars. In addition some non-mainstream sects of Islam — such as the Mu'tazili, Zaidiyah, and Quranists, and more recently the Ahmadiyya — have rejected "naskh" on the rationalist grounds that the word of God can not contain contradictions. Other scholars did/do not dismiss the theory of naskh but consider it poor scholarship.
One medieval scholar we know about — Abu Muslim al-Isfahani (d. 322/933) — "denied the theory of naskh entirely". 
More recently there have been Aslam Jairajpuri (d. 1955), and Modernist Syed Ahmad Khan (d. 1439/1898), revivalist scholar Mohammed al-Ghazali, Khaleel Mohammed, and contemporary scholar Ahmad Hasan.
According to David Powers, Islamic scholars have asked how an eternal, all-knowing, all-powerful God, would need to change His mind, i.e. His eternal divine will, and would reveal rulings wrong or imperfect in the first place. 
Islamic modernist scholars, (according to scholar Karel Steenbrink), consider the theory of naskh "an insult to the integrity and value of the uncreated revelation of God."
Hasan believes the theory of abrogation of the Quran contradicts its "eternal validity". Mohammed al-Ghazali quotes "jurist and historian", al-Khidri, as "categorically rejected" naskh of Quranic verses, saying abrogation "does not occur except to make specific, or limit, or explain that which is otherwise general and unconditional." Mohammed al-Ghazali also quotes Rashid Rida as quoting the first part of Q.2:106 — "We do not abrogate (naskh) a sign or cause it to be forgotten" — in his opposition to naskh. Syed Ahmad Khan "vehemently" rejected abrogation of Islamic revelation.
Some Muslim scholars (Al-Sha`rani and Shah Wali Allah) were skeptical of the use of Naskh, considering it a sort of short cut to be avoided. According to contemporary scholar Jonathan A.C. Brown, The Sufi jurist Al-Sha`rani considered claims of abrogation to be 
the recourse of those mediocre and narrow-minded jurists whose hearts God had not illuminated with his Light. They could not perceive all the interpretive possibilities in the words of God and the Prophet … By taking the shortcut of stamping Quranic verses or Hadiths 'abrogated', such ulama had restricted the interpretive plurality that God had intended in the Shariah. For Sha’rani only when a Hadith included the Prophet's own clear abrogation, like his report about visiting graves, could it be considered Naskh.
Shah Wali Allah was similarly skeptical of the ulama's excessive indulgence in abrogation to explain the relationship between Quranic verses or hadiths. In all but five cases, he found explanations for how to understand the relationship between scriptural passages without recourse to abrogation.
Although not a denier of naskh, Abdul-Rahim notes that 
not only were the early Muslims unable to agree on every alleged instance of naskh, they also could not agree on the details of the alleged instances, the number of instances; and the classification of the instances.
Among the arguments Islamic Modernist mufti Muhammad Abduh offers against naskh of the Quran (mentioned earlier) is that “the Quran nowhere announced that verse so-and-so is naskh, or that verse such-and-such is Mansukh”. Nor is Naskh an article of faith of Islam, like belief in the prophets, angels, books of Allah. It is "merely a technique employed by the exegetes of the first century."
Since an abrogating verse must have been revealed after an abrogated verse, being able to determined which verse came first is crucial, but (according to Abduh) scholars do not
 “possess an undeniable indication that one verse is earlier or later than any other verse, ... They merely asserted without proof that one verse was later than another. ... even more surprising is the absence of a single agreed hadith from the Prophet which might be taken to be a certain documentary proof that verse so-and-so is the nasikh of verse so-and-so.”
This raises the question of whether human scholars deciding what had been abrogating are not introducing a "man-made" element into divine revelation.
Non-Muslim.
John Burton argues that the theory of naskh was an "invention of fiqh scholars", used not to develop fiqh but to validated already existing fiqh doctrine.
A "careful examination of the Quran itself produces no evidence that naskh of the sort fiqh scholars had in mind is envisioned in or exemplified by the Quran." This sort of naskh would be the "classical" form of abrogation, namely abrogation of rulings but not text as (1. "naskh al-hukm dūna al-tilāwa"). But if this was the case, would not Q.2:106 read: 
... instead of what it does say: 
Furthermore, Burton argues (according to Bernard Weiss) that rather than fiqh scholars deciding which of two (or more) conflicting verses should be the basis of a ruling in Islamic law by determining which verse came later, the scholars searched for "text that supported" an already established doctrine of Islamic law and then postulating "a chronology" whereby that supportive text came "later and the non-supportive text earlier".
Defense.
The principle of "naskh" is acknowledged by both Sunnis and Shī'a, and the vast majority of their scholars accept that there are significant contradictions within the Quran, within the Hadiths, between the Quran and the Hadiths, and that the doctrine of abrogation as revealed by the Quran is necessary to establish Sharia.
Scholar Roslan Abdul-Rahim defends the concept of naskh pointed out the numerous Islamic scholars who have studied and written on the subject and how "very elaborate, sophisticated and ... complex" scholarly discussion of naskh became. "Over seventy" scholars — both classical and contemporary — have written "solely on naskh". Critics have noted the lack of consensus on what verses or Quran and hadith are abrogated, but Abdul-Rahim replies that while "the Muslim scholars of antiquity" may have disagreed about what revelations of the Qur’an were abrogated, at "the conceptual level of definition" they agreed.
He asks rhetorically "How could a long tradition established by a community bounded by faith and integrity, and supported by continuity and sustainability be so wrong? ... Could they have not understood or simply misunderstood something that is naturally ingrained in the language of their own culture?" While it is true that scholars have not been able to agree on the instances, number, details or classification of naskh, this is no reason to conclude that naskh "as a theory and a phenomenon is false". and he quotes philosopher of science Thomas Kuhn: “failure to achieve a solution discredits only the scientist and not the theory,” 
Some orthodox scholars, such as Ibn Hilal al-Nahwi found the theory so crucial to Islamic belief that they declared takfir against those who opposed it. Eleventh century scholar Ibn Hilal al-Nahwi (mentioned above) declared that "whoever says" that there is no abrogation in Islam "is not a believer, but rather a "kafir"," and "must renounce his position or be killed".
More recently, Abd al-Aziz ibn Baz (Wahhabi scholar and Grand Mufti of the Kingdom of Saudi Arabia at the time), responded to an article which included some ideas against the concept of abrogation, by stating that the author was guilty of "an act of clear disbelief, a repudiation of Islam, and denial of Allah the Glorious and His Prophet on whom be peace ... It is obligatory upon the governing authority to have that man brought to the courts and ask that he retract his statements, and to rule upon him according to that which the pure Shari'ah summons". (Ibn Baz having called for the execution of Muslims guilty of what he considered acts of unbelief on other occasions.)
Alternative Theories.
Among those who deny the orthodox theory of "Naskh" out of concerns over how God would change his eternal will, some Islamic scholars have used rationalization and reinterpretation to deal with contradictory verses. In addition, theories have been developed as to how to deal with contradictions in the Quran and/or Sunnah, and what Q.2:106 ("None of Our revelations do We abrogate or cause it to be forgotten, but We substitute something better or similar ...") is referring to if not orthodox naskh of the Quran.
As mentioned above, the idea that Islamic revelation abrogates earlier Jewish and Christian religious laws handed down by monotheist messengers before Muhammad, is widely accepted among Muslims.
However, an argument advanced by (at least some of) the minority of scholars who oppose the idea of abrogation of the Quran is that "naskh" in Q.2:106 refers to "only" to "the abrogation of the codes of law revealed to the earlier Prophets", and "not" to abrogation of the Quran. John Burton, Muhammad al-Ghazali, Ahmad Hasan argue that the abrogation verse Q.2:106 was revealed after a series of verses talking about the People of the Book.
Burton notes that the verses, among other things, abrogated many aspects of the Jewish Halakha. According to Muhammad Sameel ‘Abd al-Haqq, there are "many" commentators and other scholars who believe that in ayah Q.2:106 ("None of Our revelations do We abrogate or cause it to be forgotten, but We substitute something better or similar ...") the phrase "Our revelations" refers to the revelations "before" the Qur’an; "something better or similar" refers to the Quran itself. According to Mohammed al-Ghazali, "The revelation of the Qur'an, ... is an abrogation of some of the legislation of the People of the Scriptures (Jews and Christians). ... There is no contradiction in the Qur'an whatsoever ..."
Ahmad Hasan writes: "If we read this passage (Q.2:106) with reference to its context, there remains no doubt that the Qur'an is speaking about the annulment of the Law revealed unto the Prophets of the Children of Israel".
As to why "some of the most eminent authorities of "tafsir"" have not agreed with this explanation, he argues it is because
However, to believe Q.2:106 and Q.16:101 are referring to verses in the Quran, Hasan says,
is an error. "Ayah" literally means 'a sign', token, or mark by which a person or thing is known and is synonymous with "`alamah". It, by implication, also means 'a message, or communication sent from one person or party to another' and is in this sense synonymous with "risalah".
Resolving contradictions without chronology.
Two theories have been proposed to deal with contradictory commands of revelation without the chronology of verses and the abrogation of earlier ayat in favor of later ones:
The Quran has been divided by scholars into those verses revealed while Muhammad was in Mecca (the Meccan surah) preaching to develop a following, and those revealed after he left Mecca to govern the city of Medina (the Medinan surah). Sudanese Islamic scholar Mahmoud Mohammed Taha has advanced the idea that the Meccan surah contain "the basic and pure doctrine of Islam", and should form the "basis of the legislation" for modern society. These Meccan verses give more prominence to the position of women and praise other prophets and their communities — i.e. Jews and Christians. Taha argues that the Medinan surah, though revealed later in the mission of Muhammad, are not corrections of Meccan revelations but contain specialized commands/doctrine, "compromises" for the political climate, which while appropriate for their time are not eternal and are not necessarily appropriate for the 20th or 21st century.
Ahmad Hasan argues that since the Quran is valid for eternity, the solution to any contradictions found within it is not to abrogate earlier verses, but to recognize that Qur'anic revelations varied to keep "pace with the changing conditions and environment" and must be studied and applied to their "historical context". In the case of the Meccan surahs that ask "Muslims to be patient and to tolerate the aggression of the infidels" (for example: Q.2:109; Q.6:106; Q10:109; Q15:85; Q29:46), and which conflict with the Medinan Sword Verse (Q.9:5) that calls on Muslims to attack "the infidels and kill them wherever they are found"; neither is a pure/basic doctrine, nor a temporary tactic. The Meccan surahs were revealed when the Muslims were/are weak and could not retaliate against aggression, Medinan surahs when Muslim were/are strong. The proper command to implement is the one for "conditions similar to those in which they were revealed" — apply the Sword Verse when Muslims are strong, the earlier verses when they are not. Mohammed al-Ghazali also states, "There is no contradiction in the Qur'an whatsoever, for every verse has a context within which it functions. ... He, the Legislator who knows the conditions in which the verses may be applied, and it is in this manner that the Qur'anic verses are to be considered in light of the state of human affairs — with wisdom and exhortation."
In their rejection of the theory of "naskh" the Ahmadiyya also argue that a ruling is considered valid not because it was revealed after any other on a given subject, but because it is most suited to the situation at hand. Ahmadiyya believe all Qur'anic verses have equal validity, in keeping with their emphasis on the "unsurpassable beauty and unquestionable validity of the Qur'ān", but in Ahmadī "fiqh" rulings apply to the specific situation for which a verse/hadith was revealed
Literature.
In addition to being discussed within general works of jurisprudence, "naskh" generated its own corpus of specialized legal manuals. These treatises invariably begin with an introduction designed to impress the importance and high Islamic credibility of the science, often by an appeal to "'ilmic" authority figures of the past (as in the story of 'Alī and the Kufan preacher). As is made clear in these stories, "none may occupy judicial or religious office in the community who is not equipped with this indispensable knowledge and who is incapable of distinguishing nāsikh [abrogator] from mansūkh [abrogatee].
The remainder of the introduction then typically treats the various modes of "naskh", "naskh" 's applicability between Sunnah and Qur'ān, and- in appeasement of theological scruples- why "naskh" is not the same as badā', or inconstancy of the Divine Will. Following this comes the core of the treatise, an enumeration of abrogated verses in "sūra" order of the Qur'ān. In their consideration of "nāsikh wal-mansūkh" the taxonomic predilections of these authors comes out, evinced in their discussions of special verses considered "marvels" ("'ajā'ib") of the Qur'an, such as the verse which abrogates the greatest number of other verses (Q.9:5), the verse which was in effect longest until it was abrogated (Q.46:9), and the verse which contains both an abrogatee and its abrogator (Q.5:105).
