Making Mus'haf

See also: Mus'haf and Tahrif
According to Shia and some Sunni scholars, Ali compiled a complete version of the Qur’an mus'haf [2] immediately after Muhammad's death. The order of this mus'haf differed from that gathered later during Uthman's era. Despite this, Ali made no objection or resistance against standardized mus'haf, but kept his own book.[52][56]
After seventy reciters were killed in the Battle of Yamama, the caliph Abu Bakr decided to collect the different chapters and verses into one volume. Thus, a group of reciters, including Zayd ibn Thabit, collected the chapters and verses and produced several hand-written copies of the complete book.[52][57]

In about 650, as Islam expanded beyond the Arabian peninsula into Persia, the Levant and North Africa, the third caliph Uthman ibn Affan ordered the preparation of an official, standardized version, in order to preserve the sanctity of the text (and perhaps to keep the Rashidun Empire united, see Uthman Qur'an). Five reciters from amongst the companions produced a unique text from the first volume which had been prepared on the orders of Abu Bakr and which was kept with Hafsa bint Umar. The other copies already in the hands of Muslims in other areas were collected and sent to Medina where, on orders of the Caliph, they were destroyed by burning or boiling. This remains the authoritative text of the Qur’an to this day.[52][58][59]
The Qur’an in its present form is generally considered by academic scholars to record the words spoken by Muhammad because the search for variants in Western academia has not yielded any differences of great significance and because, historically, controversy over the content of the Qur’an has never become a main point.[60]
