One of the most common myths about the Qur'an, is that Usman (r.a.), the third Caliph of Islam authenticated and compiled one Qur'an, from a large set of mutually contradicting copies. The Qur'an, revered as the Word of Allah (swt) by Muslims the world over, is the same Qur'an as the one revealed to Prophet Muhammad (pbuh). It was authenticated and written under his personal supervision. We will examine the roots of the myth which says that Usman (r.a.) had the Qur'an authenticated.
1. Prophet Muhammad (pbuh) himself supervised and authenticated the written texts of the Qur'an
Whenever the Prophet received a revelation, he would first memorize it himself and later declare the revelation and instruct his Companions (R.A. ? Radhi Allahu Taala Anhu) ? May Allah be pleased with him who would also memorize it. The Prophet would immediately ask the scribes to write down the revelation he had received, and he would reconfirm and recheck it himself. Prophet Muhammad (pbuh) was an Ummi who could not read and write. Therefore, after receiving each revelation, he would repeat it to his Companions. They would write down the revelation, and he would recheck by asking them to read what they had written. If there was any mistake, the Prophet would immediately point it out and have it corrected and rechecked. Similarly he would even recheck and authenticate the portions of the Qur'an memorized by the Companions. In this way, the complete Qur'an was written down under the personal supervision of the prophet (pbuh).
