Deborah wrote: But Abraham is the father of the jewish, christian and islamic nations.
and Abrahams god is our god, therefore the three faiths are based on the same god, it's the understanding of who god is and what he is like that differs.
At what point does someone's "understanding of who God is and what he is like", when it differs from that which we can read about God in the Scriptures, become a false god and an idol?
I think the answer to that question is the one that must decide between our Christian God and any other god, including Allah, being the true God... or another religion's god being some incomplete representation of the true God.
Here is a quote from Dr Mark A. Gabriel in his book
Islam and the Jews:
The original source for the prophet Muhammad's stories about Abraham and the other prophets is the Bible. I do not think the Qur'an is a new revelation from the same God who inspired the Bible. One reason is that the Qur'an and the Bible are often contradictory. I do not think God would choose to give new information that would contradict the record that He has established thousands of years earlier.
The god Muhammad proclaimed does not exist. Muhammad's revelations came from demons. The name Allah was used in pre-Islam Arabia to refer to one of the 360 idols in Kaaba. Allah was supposed to be the greatest god. Some tribes used the name to refer to the moon god.
I believe that Muhammad presented stories and principles from Scripture as part of his strategy to win over Jews and Christians. If he built his new religion on the foundation of Judaism and Christianity, he could get more converts.
So why are there differences between the Qur'an and the Bible? I believe that Muhammad introduced differences that he felt would support Islam. I think he truly expected the Jews to accept these changes. They did not.

The account in the Bible of our Christian God and who He is, and the account of Allah in the Qur'an, demonstrates very clearly and without a doubt that the two cannot possibly be one and the same.
Allah does not even come close as another person's "understanding of who god is and what he is like" when compared to our Christian God.
