Is it permissible to deal with the jinn for the purpose of treating those possessed, within the limits of the Shari'ah?

The Shaykh : I have been asked repeatedly and over and over: Is it permissible to deal with the jinn? Glory be to Allah, a new form of misguidance is now spreading among the ranks of Muslims due to their ignorance of their religion. This question, "Is it permissible to deal with the jinn?" is comparable to, and very close to, the question we have also been asked for a long time: "Is it permissible to deal with the Christians?" I say, yes, it is permissible to deal with the Christians, because the Messenger dealt with them, but within the limits of the Shari'ah. So now the question comes: Is it permissible to deal with the unseen world, with the jinn? How is this question... does it come in the name of Ahmad or George, or with names for which Allah has not sent down any authority? What is this...? Do you know if he is a Muslim or a disbeliever? And if he is a Muslim, is he righteous or wicked? These are questions that follow one another without an answer. Why? Because, as they say in modern expression, they are behind the material. How can you deal with a world that you do not see, while it sees you? So you are beneath them, like... beneath the microscope. Your enemy sees you, and you do not see him. How can you deal with him? It is not permissible. What you call today and ask about, dealing with the jinn, is not permissible except within the limits: if a patient is brought to you who is stricken with epilepsy, and it is likely that the doctor, or material medicine which treats all material diseases with material treatments, is unable to treat this person who is afflicted with epilepsy, then at that time you recite for him what is easy of the Qur'an, and perhaps Allah (Mighty and Majestic) will cure him. Beyond that, it is not permissible. Those who exceed this Shari'ah limit are among the fortune-tellers, so it is not permissible to seek their help or to visit them, due to his saying (peace and blessings be upon him): . The fortune-teller in the past had a companion from the jinn. Look how much the misguidance has developed. The fortune-teller in the time of the Messenger had a companion from the jinn. This jinni would steal the hearing from the sky, then come and throw what he heard into the ear of his human companion. But what was heard was one thing, and a hundred things were added to it. So this human companion would hit the mark with that one thing when he reported it, and miss with the hundred. Now, he connects directly with the jinni. The jinni tells him whatever it wants, and he receives the news from him with a sound heart, as if he were a human of his own kind, having lived with him for years, and his soul has become at ease with him and he has tested him. We, by Allah... are testing people for long years, then... after long years, we are...
