My daughter suffers from Mass (possession by the Devil) and she does strange things. Is it permissible to go to someone who treats Mass with the Quran?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu 'alyhi wa sallam, is His slave and Messenger.

If a person is affected by a magic spell or is possessed by Jinn, it is permissible to go to righteous people who are well versed in treating diseases using Ruqyah (healing with the Quran and Prophetic supplications); however a person must not go to magicians and soothsayers.

I advise this sister to:

Allaah Knows best.
