Both groups realized that the feces were heading towards the fan, and they were both praying their hearts out to their respective gods for strength. Those hijackers were religious, that much can't be denied. Greengrass did not want the viewers to forget the driving force behind what the hijackers were doing, and he wanted to show where the courage to resist them came from.

I think he was also subtly communicating that, whatever god the Muslims were praying to, it was NOT the same God that the passengers prayed to. The Muslim god was a god of death and butchery

The Muslim god was a god of death and butchery...

They have no way of knowing (islam prohibits examination)...but their allah is the "destroyer." Allah is anything but the Creator. Allah is a cheap and angry pretender...allah is the "prince of darkness"...he is the anti -God, allah is hatred personified.

IMHO!
