The implication was that he was the last in the series of prophets, the last reveler of divine truth.

Even at this early date, variations in the Koranic revelations were becoming common in different parts of the new Islamic empire. So that there would be a definitive version, the Caliph `Uthman (the caliphs were successors of Muhammad) commissioned one of the Prophet's followers, Zayd ibn Thabit, and others to sort through and pull together all the material and compare it with the remembrances of those who had learned it by heart.
