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, sallallaahu ‘alayhi wa sallam, is His slave and Messenger. Dealing with the Jinn is impermissible even if it does not include seeking their help, as is claiming to know the unseen or practicing magic, because they all may lead to Shirk (polytheism). In other words, it may cause one to seek the Jinn’s help in what is impermissible or to believe in their supernatural abilities. This is something that may result in weakening one’s reliance upon Allaah The Almighty, and may cause people to be attached to the person who deals with the Jinn. In addition, it is not proven that the Prophet, sallallaahu ‘alayhi wa sallam, and his Companions dealt with the Jinn. Had it been something good, they would have been the first to do it. The effect of magic cannot be neutralized with the help of the Jinn, but by the Sharee‘ah-approved Athkaar (words of remembrance) and supplications, whether from the Quran, the Sunnah (Prophetic tradition) or by comprehensible Arabic words. Nonetheless, one must never believe that such supplications are cures in themselves for they are only a means; Allaah The Exalted is the only Curer. Once, when the Prophet, sallallaahu ‘alayhi wa sallam, became ill, Jibreel (Gabriel) recited Ruqyah (Quranic healing) over him. [Muslim, Ahmad, At-Tirmithi and Ibn Maajah] It was also narrated that the Prophet, sallallaahu ‘alayhi wa sallam, was once bewitched by a Jew named Labeed ibn Al-A‘sam. Two angels came to the Prophet, sallallaahu ‘alayhi wa sallam, and informed him of the place where the magic spell was hidden and he ordered that it be brought out. [Al-Bukhari and Muslim] This indicates the impermissibility of seeking the help of the Jinn in nullifying the effect of magic or in anything else. Your relative must note that she is at the doorstep of a serious kind of Fitnah (tribulation), and thus, she must be very cautious and must stop dealing with the Jinn who claim to be good. Most probably, this is only a way of winning her over and ultimately they will lead her astray, for the Jinn are known for their lying and deception. Allaah Knows best.
