Yes, muhammed was something else. He married a very wealthy widowed older woman (no, her name wasn't Teresa) and carried off a personally very successful con game. It's interesting that polygamy didn't enter into muhammed's revelations from allah until after the old widder died, but I digress....
Muhammed was illiterate but sharp, and came in contact with many Jews and Christians. The Quaran, his blessed messages from whatever, is a badly jumbled mishmash of poorly remembered Jewish and Christian teachings, and became more violent as his personal circumstances changed.
It's kinda how I see Mormonism. It speaks of Jesus, quotes him, but it's an entirely different character than in the NT
He had the same spirit and tactics as Joseph Smith, but different locations, different times, etc.
