Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Qais bin Abi Hazim. He says that a man came to the blessed service of the Messenger of Allah, peace and blessings be upon him, and said: I performed ruqyah (spiritual healing) on such-and-such a person who was afflicted with madness. I was given a flock of sheep in return, while I performed the ruqyah only through the Holy Qur'an. Upon this, the Prophet, peace and blessings be upon him, said: "Whoever took (a reward) through a false amulet, (let him be concerned), but indeed you have taken it for a rightful ruqyah."
