From Wikipedia:
Muslims believe that jinn are real beings. The jinn are said to be creatures with free will, made of smokeless fire by God [...], much in the same way humans were made of clay. In the Qur'an, the jinn are frequently mentioned and Sura 72 of the Qur'an named Al-Jinn is entirely about them. In fact, the prophet Muhammad was said to have been sent as a prophet to both "humanity and the jinn."
The jinn have communities much like human societies, they eat, marry, die etc. They are invisible to humans, but they can see humans. Sometimes they accidentally or deliberately come into view or into contact with humans.
Jinn are beings much like humans, possessing the ability to be good and bad. They have the power to transform into other animals and humans, and they are known to prefer the form of a snake. ...
Evil beings from among the jinn are roughly equivalent to the demons of Christian lore. ...
Christian lore... thats a funny phrase. never heard anyone say that.... other than some crusty old babbling philosphy professor from city college...
I can't even say that outloud without laughing. As if Christianity is a made up tale. Kind of silly to compare the two that way.
Just thought that was interesting.
