What is the interpretation of a person feeling jinn in their body and having partial control over them, while believing that healing is solely in the hands of God, and committing to righteousness despite falling into some sins? And what is the advice in this situation?

The touch of jinn is a reality, but it does not mean that every seizure or sensation in the body is due to it. It may have an organic cause or be mere delusions.

Therefore, do not pay attention to the whispers of Satan. You should perform ruqya (exorcism) on yourself using the Book of Allah, for it is beneficial whether there is a touch of jinn or not. There is no harm in going to someone who practices ruqya shar'iya and is known for their uprightness and avoidance of charlatanry.

Seek help from Allah, supplicate, and humble yourself before Him so that He may protect you from the schemes of human and jinn devils. Allah is capable of freeing you from suspicions, delusions, and harmful realities.
