"It is true that Muhammad started from the east and came to the west, as the sun travels from east to west. Nevertheless he came with war, knives, pillaging, forced enslavement, murders, and acts that are not from the good God but instigated by the chief manslayer, the devil."
Saint Gregory Palamas, 14th century Byzantine Saint
