Would strongly resent that reference. In Islam, Allah is all-powerful, and thus would never take human form. For that reason Jesus Christ is relegated to the status of prophet (subordinate to Muhammad, of course). "I am God" would be outrageous blasphemy to a Muslim.
Yeah but you can lie to an infidel and it's ok...so maybe he was 'just doing it for effect.'
And for that reason would be very effective misdirection if the killer is a Moslem.
And I don't think saying that would count as a sin if it is done in the cause of jihad. Remember that the hijackers drank alcohol, went to strip joints, and ate takeout Chinese food (laced with pork).
This is correct. An observant Muslim (or even one who is somewhat less than observant) would NEVER say that.
