The Qur'an is the central religious text of Islam, also sometimes transliterated as Quran, Koran, Qur'an, Coran oral-Qur-an. Muslims believe the Qur'an to be the verbal book of divine guidance and direction for mankind. Muslims also consider the original Arabic verbal text to be the final revelation of God.

Islam holds that the Qur'an was revealed from Allah to Muhammad orally through the angel (Gabriel) over a period of approximately twenty-three years, beginning in 610 CE, when he was forty, and concluding in 632 CE, the year of his death.Muslims further believe that the Qur'an was memorized, recited and written down by Muhammad's companions after every revelation dictated by Muhammad. Most of Muhammad's companions--tens of thousands, learned the Qur'an by heart, repeatedly recited in front of Muhammad for his approval or the approval of other Sahaba Muhammad had approved. The companions also compiled it in written form while Muhammad was alive. Muslim tradition agrees that although the Qur'an was authentically memorized completely by tens of thousands verbally, the Qur an was still established textually into a single book form shortly after Muhammad's death by order of the first CaliphAbu Bakr suggested by his future successor Umar. Hafsa, Muhammad's widow and Umar's daughter, was entrusted with that Quran text after the second Caliph Umar passed away. When Uthman, the third Caliph, started noticing differences in the dialect of the Qur'an, he requested Hafsa to allow him to use the Qur an text in her possession to be set as the standard dialect, the Quraish dialect aka Fus'ha (Modern Standard Arabic). Before returning that Qur'an text to Hafsa, Uthman immediately made several copies of Abu Bakar's Qur'anic compilation and ordered all other texts to be burned. This process of formalization of the orally transmitted text to Abu Bakar's Qur'anic text is known as the "Uthmanic recension" The present form of the Qur'an text is accepted by most scholars as the original version compiled by Abu Bakr.
