This is a demon, and also is called the “Satan” of the Mohammedans. It is claimed that once he was an inhabitant of Azazil, the heaven nearest God; and when the angels were commanded to bow down to the first man, Eblis was the leader of those who rebelled. After they were cast out of Azazil, Eblis and his followers were sentenced to suffer in hell for a long time. It was supposed that Eblis was composed of the element of fire, and quickly succeeded in the government of the world. A.G.H.
