Sunan Ibn Majah 3526

It was narrated from Ibn ‘Abbas that, for fever and all kinds of pain, the Prophet (ﷺ) used to teach them to say:“Bismillahil-kabir, a’udhu billahil-‘Azim min sharri ‘irqin na’ar wa, min sharri harrin- nar (In the Name of Allah the Great, I seek refuge with Allah the Almighty from the evil of a vein gushing (with blood) and the evil of the heat of the Fire.” (One of the narrators) Abu `Ammar said: “I differed with the people on this, I said: ‘Screaming.’” Another chain from Ibn `Abbas, from the Prophet (ﷺ) with similar wording, and he said: “From the evil of a vein screaming (with blood).”
