Demon
The contemporary Roman Catholic Church unequivocally teaches that angels and demons are real beings rather than just symbolic devices. The Catholic Church has a cadre of officially sanctioned exorcists which perform many exorcisms each year. The exorcists of the Catholic Church teach that demons attack humans continually but that afflicted persons can be effectively healed and protected either by the formal rite of exorcism, authorized to be performed only by bishops and those they designate, or by prayers of deliverance, which any Christian can offer for themselves or others.
Exorcism in Islam
Prohibited techniques often utilize "shirk", which is found in practices that prepare amulets or talismans. This is prohibited because "shirk" is the sin of practicing idolatry or polytheism i.e. the deification or worship of anyone or anything besides the singular God. Many times Qur'anic verses are added throughout the recitation when using these objects in order to 'mask' their "shirk". However, God believes he has provided sufficient cures in executing an exorcism, therefore exorcists should not have to rely on methods involving "shirk". Additionally, individuals seeking exorcism should avoid magicians or soothsayers because these magical practices go against Islamic Law.
