Reference: Fataawa al-‘Aqeedah – Page 584, Question 625
Question: Is it permissible to take a woman afflicted with black magic to one of the shaykhs so he can recite upon her?
Response: If the shaykh is known to be upright and religious, and of sound ‘aqeedah, and will recite the Qur.aan [upon her] whilst maintaining her complete hijaab and without being alone with her, and that the shaykh is cautious of any fitnah, then there is no harm in that, so long as there is no danger.
If, however, this person is not known for having sound ‘aqeedah, then you should not go to him; And if he was lenient in matters related to women, and touching them and looking at them, then do not go to him due to the presence of fitnah in that.
