According to Islam Djinn (Ginn) ;also known as genies are not human, but spirits that have a free will to believe or not. Muslims are afraid of them and a lot of them have violent encounter with them.  The Quran mentions Djinn in Sura 72, It says that they are different than angels.  Christians believe that they are demons and we have the power to pray and set people free from that.  Missionaries do that in Middle Eastern countries.  The Gospel has the power to set people free.
