AZA'ZEL, one of the ginn or jinn, all of whom were made of "smokeless fire," that is, the fire of the Simoom. These jinn inhabited the earth before man was created, but on account of their persistent disobedience were driven from it by an army of angels. When Adam was created, and God commanded all to worship him, Azâzel insolently made answer, "Me hast Thou created of fire, and him of earth; why should I worship him?" Whereupon God changed the jinnee into a devil, and called him Iblis or Despair. In hell he was made the standard-bearer of Satan's host. Upreared His mighty standard; that proud honor claimed Azâzel as his right. Milton, _Paradise Lost_, i. 534 (1665).
