In Islamic philosophy, ʿĀlamīn (عالمين; lit. "worlds") (genitive plural of ʿālam عالم) refers to the Universe, Worlds, or cosmos. This includes humans, plants, animals, earth, stars, jinn, devils and angels.
It is not to be confused with al-ʾAmīn (Arabic: الأمين), meaning 'the trustworthy,' which was one of the nicknames given to Muhammad.
