Caliphate

In about AD 650, Uthman began noticing slight differences in recitations of the Quran as Islam expanded beyond the Arabian Peninsula into Persia, the Levant, and North Africa. In order to preserve the sanctity of the text, he ordered a committee headed by Zayd ibn Thabit to use caliph Abu Bakr 's copy and prepare a standardised version of the Quran. Thus, within 20 years of Muhammad's death, the Quran was committed to written form. That text became the model from which copies were made and promulgated throughout the urban centers of the Muslim world, with the other versions ordered to been burnt by Uthman.

While the Shī‘ah use the same Qur'an as Sunni Muslims, they do not believe however that it was first compiled by Uthman. The Shī‘ah believe that the Qur'an was gathered and compiled by Muhammad during his lifetime.
