Mohammad's Quran?

Of course Mohammad would have said that the Quran is not his creation but Allah's. Enlightened men do not ascribe anything to themselves but to the eternal power of which they have drunk deep. You see, enlightened men drop off their ego - they would no longer have a sense of doership or ownership. Though there is much criticism of Mohammad, questioning his morals etc. - I am thoroughly in love with his personality. His rambunctiousness appeals to me - quite like Krishna. However, I think he had lapses in his spiritual quest - which alone can explain many verses in the Quran that seem rather narrow in application.
