1Sahil B = ""As the “the supreme Arab event,” to quote Kenneth Cragg, the Quran is regarded by most Muslims as Muhammad’s sole miracle. Like the prophets who came before him, Muhammad was repeatedly urged to prove his divine mission through miraculous acts. But whenever he was challenged in this way, he insistedthat he was nothing more than a messenger, and his message was the only miracle he had to offer. And unlike the miracles of other prophets, which are confined to a particular age, Muhammad’s miracle of the Quran would, in the words of the twelfth-century mystic Nadjm ad-Din Razi Daya (1177–1256), 'remain until the end of the world.'"-No god but God, Reza Aslan "
