I've concluded that Allah, as used by Islam, is nothing more than a convenient ploy to give the stamp of ethereal authority--and threat of unlimited power to punish--to whatever Mo wanted.
Pretty clever trick, actually, which is part of the reason I believe Mo did have a supernatural accomplice in his deceit--but that force has nothing to do with God.
He is called in the Bible the "Father of Lies".
#1: "I am the Lord thy God. Thou shalt not have strange gods before me." Not much wiggle room there.
