Jinn (Genii, Genie, Djinn)
Creatures that are half-human and half-demon from pre-Islamic times. Originally, they were spirits of nature that caused madness in humans. They differ not much from humans: they reproduce, they have the same bodily needs, and they die, although their life span is much longer. The Arabic word djinn, which means "spirit"", is neutral--some djinn serve Allah, while others do not.
There are five orders of genies: the Marid (the most powerful), the Afrit, the Shaitan, the Jinn, and the Jann (the least powerful).
Genies can do good or evil, are mischievous and enjoy punishing humans for wrongs done them, even unintentionally. Thus accidents and diseases are considered to be their work. They are composed of fire or air and they can assume both animal and human form. They exist in air, in flame, under the earth and in inanimate objects, such as rocks, trees and ruins. In the stories of the "Thousand and One Nights" a djinn often inhabits an old, battered oil lamp. After rubbing the lamp three times, it will appear and grants the holder of the lamp three wishes. A forth wish will undo the previous three.
