Is it permissible to go to sorcerers to undo magic, to know how the magic was done and where it is buried, and to know the person who performed the magic? Is this permissible?

Magic is a reality and a trial from Allah. Seeking treatment from it is permissible through legitimate Ruqyah (exorcism) from the Quran, supplications (Du'a), and remembrances (Dhikr), whether by performing Ruqyah on oneself or by requesting it from someone known for their uprightness. This should be done with extreme caution against soothsayers and diviners who claim knowledge of the unseen and the location or perpetrator of magic.
