What is the truth about a jinni possessing a human?

And finally. The brother Ahmad Ali Mu'awwadha asks in his letter, saying: Is it true that the jinn can enter a human body and make him speak, or speak with his voice? Please inform us, may Allah reward you.
Answer: Yes, the jinn possess a human. They possess him in a specific manner until they speak on his tongue and talk on his tongue about things where the voice of the jinni is distinguished from the voice of the human. This is a reality, both in the past and the present. It is the madman whom the jinn possess; it is the madman. The jinni speaks on his tongue, saying, "Give us this, give us something good, slaughter for us this, do such and such, you will find the money in such and such a place," with a voice that people hear which is not the voice of the human. This is something that occurs, and whoever denies it has erred. This is the possession of the jinni by the human, and by this, he becomes a madman whose mind is disturbed and agitated. When it leaves him and departs from him, his mind returns to him. Yes.
