No, because the God of islam is not the God of the Bible, He was a perverted “moon-god” of the Arabs.
Bush was not correct.
Ask a Muslim. They will say they are worshipping the God of their father Abraham. You can believe they are worshipping the moon if you want, but that's not what they believe.
I would agree they don't know Him, as they ascribe characteristics to Him that He does not have, and they believe He expects things that He does not and so on.
