Allah is not the same God as the Jewish and Christian God. It is most definitely a made up pagan God by the pedophile prophet. Well, actually, not made up but created to another level. Yes, it is a moon God that had three daughters and so on, just as a few here rightfully explained. Even worse though, it was a rock. muhammad's father ran the kabba. He was a businessman. There were hundreds of idols in the kabba that people paid to come and worship and take care of. Many different pagan Gods were stored there, and the worshippers paid rent to mo's dad. People think the pet rock was invented in the 1970's, not so, credit must go to the predecessors of islam here.
The reason most converts from islam turn to atheism is that their God is so awfully evil and they have had it, falsely, drilled into their heads, that allah is the same God as the Jewish and Christian God, that they turn from any religion. I still would rather see them as atheists then as muslims. Atheists don't want me to put up a Christmas tree, muslims want to kill me for it. I would even rather see them become satanists, heard of any satanist terrorist attacks lately?
