The ruling on anointing the one being treated with olive oil and using salt and garlic, and addressing the jinn

Question:
May Allah reward you. This questioner says: We have a student of knowledge who recently started working in ruqyah (healing by Qur'anic recitation), and we objected to him regarding certain matters, namely: Yes. He anointed the body of the one being treated with olive oil, and the oil was recited over before performing the ruqyah, and he used salt and garlic on the grounds that the jinn are affected by them, claiming that this is known through experience. He asked the jinn if there was anyone else in the house afflicted besides this possessed person? And after discussion, he did not argue that some scholars have permitted it, and the default is the permissibility of what does not involve shirk (associating partners with Allah).

Answer:
As for anointing with olive oil that has been recited over, or with water that has been recited over, there is nothing wrong with that. As for anointing with garlic and the other thing, the garlic. He mentioned something. Salt. Salt and garlic; this has no basis. And how does he know that salt and garlic affect the jinn? And what makes him know that they affect the jinn? This has no basis. And his saying that we should follow the opinion of those who said it is permissible; we say: We do not accept anything except with evidence. And what is the evidence of the one who said it is permissible? If he brings a valid evidence that does not contradict, [we accept it], but a mere statement is not something we accept. Yes.
