Angels are spiritual, supernatural beings in many religions, often seen as messengers or intermediaries between God and humanity, typically depicted as winged, humanoid figures, but also as pure spirits. They serve various roles like protectors (Guardian Angels) and divine servants, with specific names and duties in traditions like Christianity (Michael, Gabriel, Raphael) and Islam (Jibreel, Azrael). The term also metaphorically describes kind, helpful people.
