I don’t know anything about the so-called practice of exorcism; if by this term you mean spiritual healing, Islam provides resources for us. In fact, the Qur’an refers to itself as the source of healing, mercy and guidance for mankind. And mind you one of the names of Fathihah is Healer; so it has been used for purpose of healing.

For further details, let me cite here one of my earlier answers on a similar question:

“Islam teaches us that Allah alone has the absolute power to bring benefit or harm. Once this belief is firmly rooted in your consciousness, you cannot allow for such dubious notions to agitate your mind. All of us ought to reflect on the Prophet’s advice to his cousin Ibn Abbas: “My son, be mindful of Allah, Allah will take care of you…If you must ask, ask Allah; if you must seek help, seek help from Allah. You should know that if the people of the whole world were bent on benefiting you, they would never be able to do so unless Allah wills it. And know that if they were bent on harming you, they would never be able to do so, unless Allah wills it…”

Allah tells us in the Qur’an that those who submit to Allah and are committed to serving Him will never be under the permanent sway and control of the devils:

“(And yet,] behold, thou shalt have no power over [such of] My servants [as place their trust in Me]: for none is as worthy of trust as thy Lord.” (Qur’an: 17:65)

I advise you, therefore, to dismiss such thoughts and turn to Allah to dispel the whisperings of Satan:

Here are a few du’as to read for protection and healing:

Bismillaahi alladhee laa yadhurru ma’ismihi shay’un fi al-ardhi walaa fi al-ssamaa’i wahuwa al-ssamee’ al-‘aleem

(In the name of Allah; with His name nothing in the heavens or earth can do any harm. He is the All-Hearing and All-Knowing).

A’oodhu bi izzati Allaahi wa qudratihin min sharri maa ajidu wa uhaadhiru

(I seek refuge in the might and power of Allah from the evil of what I experience and fear from)

A’oodhu billaahi al-ssamee’i al-‘aleem mina al-sshaytaani al-rrajeem

(I seek protection with Allah from the evils of Satan the accursed)

Rabbi innee a’oodhub bika min hamazaati al-sshayateeni wa a’oodhu bika rabbi an yahdhurooni

(My Lord, I seek protection with You from the whisperings of the devils. My Lord, I seek refuge with You from their presence around me)

Finally, let me remind you that dhikr and du’as will have beneficial effects only if we are diligent in performing salah and reading the Qur’an.
