Kharijah bin Salat Taimi narrates from his uncle that he passed by a people among whom there was a madman who had been bound in iron. One of them said: Do you have anything by which you can treat him, for your companion has brought goodness? The narrator says: So I recited Surah Al-Fatihah over him for three days, reciting it over him twice each day, and he was cured. That man gave me one hundred sheep. He (the narrator) then went to the service of the Prophet Muhammad (peace be upon him) and mentioned this to him. The Prophet (peace be upon him) said: Eat it, for whoever eats by means of false incantations (it is forbidden), but you have eaten by means of a true incantation.
