Sayyiduna Umayr, the freed slave of Abi al-Lahm (may Allah be pleased with him), said: I presented to him (peace and blessings be upon him) the ruqyah with which I used to treat the insane in the Age of Ignorance, and he (peace and blessings be upon him) said: "Remove this from it, and remove this too, and recite only this from it."
