what year is considered the beginning of islam
Islamic calendar The Islamic calendar employs the Hijri era whose epoch was retrospectively established as the Islamic New Year of AD 622. During that year, Muhammad and his followers migrated from Mecca to Yathrib (now Medina) and established the first Muslim community (ummah), an event commemorated as the Hijra. In the West, dates in this era are usually denoted AH (Latin: Anno Hegirae, "in the year of the Hijra") in parallel with the Christian (AD) and Jewish eras (AM). In Muslim countries, it is also sometimes denoted as H[1] from its Arabic form ( سَنة هِجْريّة, abbreviated هـ). In English, years prior to the Hijra are reckoned as BH ("Before the Hijra").[2]
Birmingham Quran manuscript Professor Süleyman Berk of the faculty of Islamic studies at Yalova University has noted the strong similarity between the script of the Birmingham leaves and those of a number of Hijazi Qurans in the Turkish and Islamic Arts Museum; which were brought to Istanbul from the Great Mosque of Damascus following a fire in 1893. Professor Berk recalls that these manuscripts had been intensively researched in association with an exhibition on the history of the Quran, The Quran in its 1,400th Year held in Istanbul in 2010, and the findings published by François Déroche as Qur’ans of the Umayyads in 2013.[21] In that study, the Paris Quran, BnF Arabe 328(c), is compared with Qurans in Istanbul, and concluded as having been written "around the end of the seventh century and the beginning of the eighth century."[22]
