Can the Sidr tree be used in the treatment of jinn possession (mass) or sorcery (sihr), and what is the optimal way to treat jinn possession, especially after experiencing a state of hysteria and pain upon leaving the mosque?

If the pain is severe and unbearable and only ceases upon leaving the mosque, then it is an excuse that permits praying at home. As for the treatment of magic: take seven Sidr leaves and crush them, then mix them with water while reciting Ayatul-Kursi and Surahs Al-Ikhlas, Al-Falaq, and An-Nas. Then, the afflicted person drinks from this water and bathes with the remainder.
