All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
The Muslims who are residing in that country in general and particularly the Daa’iyahs (people calling to Allaah) among them should be interested in the ‘Aqeedah (matters of faith) of people, so they should teach them the correct ‘Aqeedah, and they should be concerned with raising their awareness and connecting their hearts to Allaah and to no one else. They should also let them know that it is only Allaah Who harms and benefits.
When those people fully rely on Allaah, have a firm certainty and a trust in Him, and be heartily attached to Him, they would not fear the devils nor care about them, rather they would know that Allaah is sufficient for them in repelling the plots of the devils and so they would leave their affair to Allaah, as He is the best protector and the best helper. Also, the Daa’iyahs should teach people the useful Ruqyah which they would perform on themselves to protect themselves from the plots of the devils and the evil of the magicians.
However, it is permissible to seek Ruqyah if the person who performs it abides by the pre-conditions of the correct Ruqyah. Besides, it is permissible for a person who performs the Ruqyah to perform it in private or in public provided that he abides by its pre-conditions, which are that it should be performed with the words of Allaah [the Quran] or with words that are clearly understood and do not include a prohibition. Also, both the person performing the Ruqyah and the one for whom it is performed should know that the Ruqyah does not harm or benefit by itself, but it is only Allaah Who harms or benefits. For more benefit, refer to Fataawa 85500, 82355 and 82918.
Allaah Knows best.
