So there is no actual excorsism in Islam? I mean a ritual of some sorts, I wanted to know because exorcism's are performed by Christians ; they're quite common.
Here's an Example of the Ritual performed.
In the name of our Lord Jesus + Christ and by His power, we cast
you out, every unclean spirit, every devilish power, every
assault of the infernal adversary, every legion, every diabolical
group and sect; begone and stay far from the Church of God, from
all who are made in the image of God and redeemed by the precious
blood of the divine + Lamb. Never again dare, you cunning
serpent, to deceive the human race, to persecute the Church of
God, nor to strike the chosen of God and to sift them as + wheat.
For it is the Most High God who commands you, + He to whom you
heretofore in your great pride considered yourself equal; He who
desires that all men might be saved and come to the knowledge of
truth. God the Father + commands you. God the Son + commands you.
God the Holy + Spirit commands you. The majesty of Christ, the
eternal Word of God made flesh + commands you; He who for the
salvation of our race, the race that was lost through your envy,
humbled Himself and became obedient even unto death; He who built
His Church upon a solid rock, and proclaimed that the gates of
hell should never prevail against her, and that He would remain
with her all days, even to the end of the world. The sacred
mystery of the cross + commands you, as well as the power of all
the mysteries of Christian faith. The exalted Virgin Mary, Mother
of God + commands you, who in her lowliness crushed your proud
head from the first moment of her Immaculate Conception. The
faith of the holy apostles Peter and Paul and the other apostles
+ commands you. The blood of the martyrs and the devout
intercession of all holy men and women commands you.
Therefore, accursed dragon and every diabolical legion, we adjure
you by the living + God, by the true + God, by the holy + God, by
the God who so loved the world that He gave His only-begotten
Son, that whoever believes in Him shall not perish but shall have
life everlasting; cease your deception of the human race and your
giving them to drink of the poison of everlasting damnation;
desist from harming the Church and fettering her freedom. Begone
Satan, you father and teacher of lies and enemy of mankind. Give
place to Christ in whom you found none of your works; give place
to the one, holy, Catholic, and apostolic Church, which Christ
Himself purchased with His blood. May you be brought low under
God's mighty hand. May you tremble and flee as we call upon the
holy and awesome name of Jesus, before whom hell quakes, and to
whom the virtues, powers, and dominations are subject; whom the
cherubim and seraphim praise with unwearied voices, saying: Holy,
holy, holy, Lord God of hosts!
That's the Roman Ritual, it's quite Ancient; other Christian Denominations have other forms of doing excorsism but I am not that familiar with them.
