if you want to make a lie believable you mix in just enough truth to make it sound real. He did start off studying Christianity and did read the bible from what I have read about him. I guess his need to have sex with young girls made it necessary for him to form a new religion; something Christianity would never have approved of.
Nowhere in either book of the Bible does it proscribe women from showing their hair, but that's a very old SECULAR tradition from many different civilizations, that died off long ago, for Most Jews and most Christians. Not so with the Muslims, who regressed in the 1950s in Egypt; for POLITICAL, not "religious" reasons.
