Not so surprising that that Muhammed guy (peace be upon him! (0)) got inspired for his wars. Apparently he was illiterate, but it seems that somebody read him big parts of OT. Muslims believe it was an angel named Gabriel (3), not to be confused with Moroni (4) that appeared in the US. And when we're there, Americans should understand Muhammedans and vice versa, as the US president was directly instructed by God too (5) so much for the Separation of church and state (6).
