Angels in Islam are made of light, have no free will, and are an article of faith rather than folklore — belief in them is listed among the six pillars of iman. Named ones have specific offices: Jibril carries revelation, Mikail sustenance, Israfil will blow the trumpet, and two recording angels write each person's deeds. The theologically pointed case is Iblis, who refused to bow to Adam: the Quran calls him one of the jinn, not an angel, which preserves the rule that angels do not disobey.
