Origins of the Idea of Djinni/Spirits

Before God created Eve, he created another woman to be the first wife of Adam: Lilith. Although created as a human by God, ancient legends tell of her being born a demon and bearing various monsters and demons. Many were invisible, but always opposed to humankind. They could also be provoked by certain acts of a human individual. Some demons, although invisible, chose to manifest themselves in visible ways. The most common form of these demons were djinn.

Al-Haddin/Aladinn
Perhaps the story of Aladinn in One Thousand and One Nights is based on an older Arab tale, whose hero is al-Haddin, and who fought djinn, who in the story were disembodied demons that kicked up small dust storms. They inhabited deserts and gloomy valleys.
