Allah is another name for Satan because ‘the Allah of Islam’ is not the true and living God...The fact of the matter is all false religions have a god or gods, and to call some entity of your own manufacturing or some demon of Satan himself ‘god’ doesn’t make it so. The Allah of Islam is not God...is not the God of Abraham, Isaac, and Jacob, is not the God and Father of our Lord, Jesus Christ.

God the true and living God is not Allah! That has to be made clear. We are not talking about the same god. They are monotheistic, they have one god, but their god is not a trinity—that is not the true god. They do not believe in God as a trinity; therefore, that’s not the true god. They do not even believe that He is the God of Abraham, Isaac, and Jacob. They believe He is the God of Abraham, whose true and legitimate heir was Ishmael...so they rewrite the Scripture.
