In Miltons Paradise Lost, Azazil is the standard-bearer of the infernal host. According to the Koran, when God commanded the angels to worship Adam, Azazil replied, Why should the son of fire fall down before a son of clay? and God cast him out of heaven. His name was then changed to Eblis, which means despair.
