What do you advise me to do after I felt stomach pain, changes in my emotions, quick temper, aversion to worship, and a feeling of impending death, after drinking water over which a شيخ (sheikh) recited [Quranic verses]?

We ask Allah to grant you well-being and safety, and we advise you to perform Ruqyah Ash-Shariah (Islamic exorcism/healing), supplicate, and be patient with both of them. Also, have a good opinion of Allah and seek out times when supplications are answered, while reciting Al-Fatihah over Zamzam water. The symptoms and signs of Jinn possession, black magic, and the evil eye, as well as how to treat them with Ruqyah Ash-Shariah, and the difference between a legitimate raqi (healer) and a charlatan, have been previously explained in prior fatwas.
