[Kirkwood]

Well, I wouldn’t expect someone to say that their god was #2.

[Jan_Sobieski]

The real meaning of the declaration is that Islam, its god, and its followers are supreme to all other beliefs, gods, and humans. This cliché is often shouted, not as a humble attribution or praise to Allah, but a warning directed at non-Muslims, to whom the declarer is expressing that the infidel will submit, either by law or by sword.

Will you submit when they shout this in your neighborhood?
