"I always took the view — contrary to most previous scholars of Islam — that the Quran was not something that Muhammad had consciously produced. For long, however, I hesitated to speak of him as a prophet, because Muslims would have taken this to mean that everything in the Quran was finally and absolutely true, which was something I did not believe. More recently, however, I have said that Muhammad is a prophet comparable to the Old Testament prophets, though with a different task, namely, to bring the knowledge of God to people without such knowledge, whereas their task was mainly to criticize the conduct of those who already believed in God."
