Exorcism of Djinn

The Djinn are said to be creatures with free will, made from 'smokeless fire' by God (the literal translation being “subtle fire”, i.e., a fire which does not give itself away through smoke), much in the same way humans were made of earth. According to the Recitation, Djinn have free choice, and Iblis used this freedom in front of God by refusing to bow to Adam when God told Iblis to do so.

By refusing to obey God’s order he was thrown out of the Paradise and called “Shaitan” (See Shaitan). In the Qur'an, Djinn are frequently mentioned and Sura 72 of the Qur'an named Al-Jinn is entirely about them. Another Sura (Al-Naas) mentions the Djinn in the last verse. In fact, it is mentioned in the Qur'an that Muhammad was sent as a prophet to both “humanity and the Djinn”.

The Djinn have communities much like human societies: they eat, marry, die, etc. They live in tribes and have boundaries. They follow religions as humans do, and follow the same ranks in armies as humans do. Djinns can settle in a vast area to a tiny hole, as they are massless and can be fit into any space they find sufficient for them. They are invisible to humans, but they can see humans.

Sometimes they accidentally or deliberately come into view or into contact with humans. Djinn are believed to live much longer than humans: some of whom are said to be still alive having seen Muhammad (who lived during the 7th century). Much like humans, Djinn have learned to assimilate into the human world when they desire to do so. In many cases they live unnoticed among people marked only by the rather unusual or somewhat secretive practises they keep. Djinn can take on the form of humans and other animals. They can also be summoned by humans.

Humans attempting to perform black magic on humans call Djinn specializing in dirty deeds to perform the magic. Such black magic on humans (to influence a marriage to end in divorce, etc) can only be undertaken by dark Djinni in exchange for money. Thus, a person often pays a magician, who then calls upon a dark Djinn, who then performs the magic. These acts are considered haraam in Islam
