Wiki has some interesting things to say about it, Kendall.

So does this guy, from a quick scan, though I am NOT sure of his veracity or motivation in writing his paper. I will have to read it over more carefully: click here.

Even MORE interesting stuff here at the Islam Review which makes it seem clear they are not one and the same, from what I have quickly gathered. Need to read it in more depth, too.

ON THE OTHER HAND! ISlam on Line says the following:

The God of the Qur'an is the same as the God of the Torah and the Gospel. Muhammad (pbuh) taught the same religion taught by all the prophets of God, including Abraham, Moses and Jesus (peace be upon them all).

Not sure anybody knows!
