Is Allah the same god of the Old Testament?

Are there any evidences or scholarly commentary supporting your answer Arsh? If so, it would be helpful to add them to the answer.

Modern Muslims commonly believe the Christian concept of God is the same as the understanding of Allah (who is not God), simply a synonym, if this is the case these Christianised Muslims must believe a man can be a God, and God is a trinity, this is the concept of a Christian personified God, the absolutely false and insane concept of the ignorant, not only is this specifically, and comprehensively denied within the Qur'an, but would be considered a Shirk.

Some modern Muslims believe the Jewish God is again simply a synonym, but you would have to believe the Jews are the only human beings of value to that God, been his chosen people, that all the non-Jewish human beings are worthless and sub-human in comparison to the Jew, so to be exploited and abused as the Jewish people feel fit, to view this perversion as true would again be a Shirk.
