It is narrated from Hazrat Uthman bin Abi Al-Aas (may Allah be pleased with him) that once I suffered from such an ailment that brought me close to death. The Prophet (peace and blessings be upon him) came to visit me and said: Place your right hand on the place of pain and say seven times: "A'udhu bi'izzatillahi wa qudratihi min sharri ma ajid" (I seek refuge in the might and power of Allah from the evil of what I find). I did so, and Allah removed my pain.
