>>Was she six years old then, or nine, or an old lady in her teens?
One of his early wives. Possibly Wife #1. The 9 year old was much later when he started collecting women and girls.
But you totally missed the point. The angel WAS a demon and he knew it, but he was talked out of knowing the truth and accepting the lie and that allowed Satan to gain a foothold in human history that he had never really had before. Islam gave him the ability to rewrite the gospel and to bring a believable evil into the world. If he had just created the “Church of Satan”, people would have pushed that away (except for very small number of kooks).
It almost seems that satan tried everything he could in the beginning of the Church persecutions but he failed. Then he went back to the drawing board and came up with a cult that would counter Christianity. The Roman emperors persecuted the Christians but they didn’t have s substitute for Christianity. Islam was a system that was a counter-Christianity.
Satan even picked a perfect place to begin his attack on Christ. He picked Arabia which was a vast tribal area with no government. This made is a divided county with many tribes fighting against each other. Mohamed gathered a group to himself and then began attacking one tribe at a time, picking the weakest tribes—the low hanging fruit. When the other tribe lost the battle Mohamed would give them an ultimatum— convert or die. In one day his army could double in size because of this tactic which is the same tactic that ISIS is still using today. After a while, he had conquered and united all of the Arabian tribes into one huge army which gave them power equal to the nations that surrounded them.
In a hundred years the muslim army had reached Spain. Mohamed’s simple but brutal tactic really worked. The muslims had an empire that rivaled Rome in much less time.
