Is it permissible to sit continuously for ruqyah, either with the Qur'an or with the well-known supplications?

The questioner : Is it permissible to sit continuously for ruqyah, either with the Qur'an or the well-known supplications, such that he performs ruqyah on those he knows need it or those who do not? And is it also permissible to sell... the ruqyah for a price, such that he buys water, for example, for one riyal and sells this water after the recitation for five riyals?

The Shaykh : It is not permissible. But you say that he uses ruqyah for those who need it and those who do not. How is that?

The questioner : People come, and whoever asks him comes. This patient, or the one who attends his gathering, has a standing gathering for ruqyah only.

The Shaykh : No problem, but does the one who comes to him need ruqyah or not?

The questioner : He does not ask, O Shaykh. Allah knows best if he needs it or not.

The Shaykh : You say this, but in any case, every question has an answer. I have answered you, but I ask you to be precise in reporting the facts. Every question has an answer, and I have answered you. Please proceed.
