List of Islamic texts

Quran.
The Quran is the central religious text of Islam, which Muslims believe to be a revelation from God. It is widely regarded as the finest work in classical Arabic literature. The Quran is divided into chapters (Arabic: سورة "sūrah", plural سور "sūwar"), which are subdivided into verses (Arabic: آية "āyāh", plural آيات "āyāt").
The text of the Qur'an of 114 chapters of varying lengths, each known as a surah. Each sura is formed from several verses, each called an ayah.
A body of commentary and explication (tafsīr), aimed at explaining the meanings of the Quranic verses.
The science which describes the reason, circumstances, and events surrounding the revelation of verses.
Sunnah.
Sunnah denotes the practice of Islamic prophet Muhammad that he taught and practically instituted as a teacher of the sharī‘ah and the best exemplar. The sources of sunna are usually oral traditions found in collections of Hadith and Sīra (prophetic biography). Unlike the Qur'an, Muslims naturally differ on the set of texts or sources of sunnah, and they emphasize different collections of hadith based on to which school of thought or branch they belong.
Hadith (Traditions of the prophet).
Hadīth are sayings, acts or tacit approvals ascribed to the Islamic prophet Muhammad.
Biographical evaluation (ilm ar-rijal).
The science which explores the narrators of hadith.
