What are the conditions for the Ruqyah practitioner and the prescribed Ruqyah?

Question:
Many questions are asked about the Ruqyah practitioner: Does he have conditions? And does the Ruqyah have conditions for it to be prescribed?

Answer:
Yes. The Ruqyah practitioner must be knowledgeable about the Shari'ah Ruqyah. He should not be ignorant and treat people out of ignorance, perhaps reading from misguided books of medicine or others and treating people with them. He must be knowledgeable about the Shari'ah Ruqyah.
He must rely on Allah, considering the Ruqyah to be merely a cause, while the Healer is Allah (Glorified and Exalted is He). Also, the Ruqyah must be in clear Arabic. He should not mutter in another language where one does not know what he is saying. It must be in Arabic if he is treating Arabs and not hiding anything from them that they do not know.
The fourth condition is that he believes that healing is from Allah, and that the Ruqyah is only one of the causes. Yes.
