Is what the religious scholar mentioned logical, that his brother is bewitched and that a female jinn who loves him is preventing him from marrying and affecting his decisions and thoughts? And how can she be stopped and removed from him, given the fear of her harming any girl he wishes to marry, or completely preventing him from marrying? We request beneficial evidence from the Quran and Sunnah.

Magic is real and has an effect, and the possession of humans by jinn is possible. The treatment for magic and jinn possession is through Ruqyah (Islamic incantation) according to Sharia. It is best for a Muslim to perform Ruqyah on themselves. If they need someone to perform it for them, they should seek out people of righteousness and integrity. Frequent supplication is also important, for all affairs are with Allah.
