Musannaf Ibn Abi Shaybah 25132 — Taking payment for ruqyah: those

Kharijah bin al-Salt relates that his paternal uncle came to the Prophet (peace and blessings be upon him). When he was returning, he passed by a mad Bedouin who was bound in iron fetters. Some people said (to his uncle): Do you have anything with which you can treat him? For your companion (meaning the Prophet (peace and blessings be upon him)) has brought what is good. So I performed ruqyah for that Bedouin with Surah al-Fatihah for three days, twice each day, and he recovered. For this those people gave me a hundred goats. When I reached the Prophet (peace and blessings be upon him), I told him about this. He asked: "Did you recite anything besides this?" I said: No. He said in reply: "Eat them, saying Bismillah. By my life, whoever has eaten by means of a false ruqyah (let him answer for it), but you have certainly eaten by means of a true ruqyah."
