Well, now, this is interesting. If we were to take the story as literal then Mohammad didn't matter at all. The Qur'an mattered yes, but that had nothing to do with Mohammad himself. He could have been a talking banana for all he mattered. Or a Skype headset. He's just a conduit for God to talk. Apparently Abrahamic Gods can't appear as people and do their own talking - that's just too much.... clarity? For the Philosophy in the Qur'an, the only person that matters here is God. Think of it like this: You meet the author of Harry Potter (by phone). She says, look, I noticed you guys over there have a bad copy. I'm going to tell you which parts to correct now. Thanks. -- who do you credit with the Book and the Philosophy of Harry Potter? The genuine Author of the Book or the secretary on the phone with the Author who is taking down the notes? Obviously the Author. In the case of the Qur'an as you know, God would be the Author, Mohammad would be the secretary. If we were to compare the entire paradigm with, say, someone like Buddha; well now, Buddha actually sat down and thought up His own ideas all by himself (under a tree according to his myth). The thing that's interesting is comparably with Islam, Allah didn't come up with anything anymore enlightening with his Omniscience than Buddha did just thinking by himself. As God knows all, how do we know he didn't just copy Buddha??? I mean, please, even modern philosophers come up with new ways of thinking about things. Regardless of what you may think in this regards, just notice that we're comparing Buddha with Allah, not Buddha with Mohammad. So, again, if one were to take the story as fact, then Mohammad could have been a talking banana, a secretary or skype head set. He isn't of any concern at all and simply doesn't matter at all. Now, if there are no Gods, this is something else to think about. Think of something YOURSELF (like Buddha) and offer it as YOUR advice - well, this is logical and rational. Pretending to hear a magical God and pretend that IT has offered some advice (or commandment) and offer this advice on ITS behalf - this is a logical fallacy: argumentum ad verecundiam (appeal to athority).
