4,000 at Rayy. A large number of soldiers disagreeing about the correct way of reciting the Quran may have caused Hudhayfah to promote a unified text. An example of the confusion at this time is seen during a campaign in Tabaristan, where one of the soldiers asked Hudhayfah, "How did the Messenger of God pray?" Hudhayfah told him the soldier prayed before fighting. It is believed upon Hudhayfah's request Uthman obtained the sheets of the Quran from Ḥafṣa and appointed a commission consisting of Zayd and three prominent Meccans, and instructed them to copy the sheets into several volumes based on the dialect of Quraysh, the main tribe of Mecca.
