Majma al-Zawaid — Hadith 8469

Hanash al-San'ani reports from Sayyiduna Abdullah (may Allah be pleased with him) that he recited into the ear of an afflicted man who had lost consciousness, and he regained consciousness. The Prophet (peace and blessings be upon him) asked him: "What did you recite into his ear?" He said: I recited: "Did you think that We created you without purpose?", and I recited it to the end of the surah. The Prophet (peace and blessings be upon him) said: "If a man with certain faith were to recite it over a mountain, it would move from its place."
Abu Ya'la recorded it; its chain contains a narrator, Ibn Lahi'ah, in whom there is weakness, and his hadith is hasan (good); the remaining narrators of this report are the narrators of the Sahih. In the chapter on the signs of Prophethood, hadiths will come which mention that, without any ruqyah, relief from madness was granted through his (peace and blessings be upon him) blessing.
