Exorcism
In Catholic practice the person performing the exorcism, known as an exorcist, is an ordained priest. The exorcist recites prayers according to the rubrics of the rite, and may make use of religious materials such as icons and sacramentals. The exorcist invokes God—specifically the Name of Jesus—as well as members of the Church Triumphant and the Archangel Michael to intervene with the exorcism. According to Catholic understanding, several weekly exorcisms over many years are sometimes required to expel a deeply entrenched demon.
Exorcism in Islam
Possession is not caused by Satan, who is said to be just a tempter, whispering evil suggestions into humans heart, but, even though not mentioned in canonical scriptures, according to folklore by jinn, who can enter a human body physically or haunting them mentally. A possession by a jinn can happen for various reasons. Ibn Taymiyyah explained a Jinn could sometimes haunt an individual, because the person could (even unintentionally) harm the jinn; urinating or throwing hot water on it, or even killing a related jinn without even realizing it. In this case the jinn will try to take revenge on the person. Another cause for jinn possession is when a jinn falls in love with a human and thereupon the jinn possesses the human. Some women have told of their experiences with jinn possession; where the jinn tried to have sexual interaction from inside their bodies. Thirdly, it occurs when a jinn is evil and simply wants to harm a human for no specific reason, it will possess that person, if it gets the opportunity, while the human is in a very emotional state or unconsciousness. Jinn may also haunt someone in service of a sorcerer.
