I have a friend who has been under the negative influence of a resident Jinn in his body for over 40 years .
It has caused him emotional distress and physical ailments. He has tried many wazaifs before. Please be advised that he is from Ahle Sunnat . He needs to get out of that stress to live a normal life. May Allah reward you for your kind help.

I believe in the existence of Jinn because Quran says but I don’t believe they cause any trouble for human. Please bring her to the Doctors and don’t waste your time.
Recite Rurah Jinn for her.
