A man who performs ruqyah (healing by Qur'anic recitation) on people and uses thorns during his ruqyah to treat sciatica: what is the ruling on his ruqyah?

Question:
He says: Honorable Shaykh, may Allah grant you success. A man performs ruqyah on people and claims to treat certain diseases by reciting the Mu'awwidhat (the chapters of protection) and supplications. All of this is in clear speech with no ambiguity, except that he uses thorns during the ruqyah. Every time he recites, he cuts some of them, and they are placed under the patient's foot. This is for the purpose of treatment, for example, for sciatica. This man does not do without these thorns in any way. What is the ruling on this ruqyah?

Answer:
Sciatica is a known disease, and its treatment by doctors is not through ruqyah; its treatment is by cupping or whatever the doctors do. People do not go to sorcerers and say, "This is a ruqyah." This is known; its treatment is known, and it is a disease known to doctors. Yes.
