Does Gabriel point out in his book that the God of Creation worshipped by Jews and Christians, and Allah, the deity worshipped by Muslims, are not the same?
I don’t know, but I certainly agree with you.
The purpose of the book is not to compare Christianity and Islam in a my God is better than your God type of discussion, even though he left Islam for Christianity.
This book is to warn all Kafirs (infidels) of the danger Islam poses to them regardless of their beliefs or non beliefs.
He makes it clear the differences in Christianity and Islam so there should be no doubt the supernatural beings are not the same in those religions. - Tom
