Those who claim that Allah is a pagan deity, most notably the moon god, often base their claims on the fact that a symbol of the crescent moon adorns the tops of many mosques and is widely used as a symbol of Islam. It is in fact true that before the coming of Islam many "gods" and idols were worshipped in the Middle East, but the name of the moon god was Sîn, not Allah, and he was not particularly popular in Arabia, the birthplace of Islam. The most prominent idol in Mecca was a god called Hubal, and there is no proof that he was a moon god.
