Allah is in fact a different name for Yahweh, the war god, kept in the ark of the covenant, released to destroy the enemies of the jews.
The same god who in the old testemant was not quite the nice old man portrayed by Jesus and the Renessaince.
Much like angels who were originally the messangers of god, or soldiers of god when needed. In fact Jacob got the name Isreal(wrestles with god) beause he wrestled with god's messanger.
If you would really like to get down to it, the argument can be made that both Islam and Christianity are both perversions of judiusm. Neither ascribing to the original covenants(such as circumsiscion) and Judiusm originally had no notion of hell or heaven. Our time was solely here on earth, serving our god(one of many).
Which brings up an interesting question. If there was only one TRUE god, why do we need a commandment telling us not to worship other gods if there are no other gods?
And how do christians resolve the changing nature of god from the OT to the NT?
