Jinn: What really lives in the bottle

The concept and existence of jinn is widely accepted in Islam. God is said to have created the jinn before humans from "hot wind" and "smokeless fire," and some jinn are Muslim. Like humans they were invested with intellect, discrimination, freedom and the power to choose between right and wrong. They live all over earth on a separate plane of existence from man and cannot easily be seen, though they are often thought to take the shape of snakes and black dogs.
