It was narrated from Ibn 'Abbas that, for fever and all kinds of pain, the Prophet P.B.U.H used to teach them to say: (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." (Da'if) (One of the narrators) Abu 'Ammar said: "I dilfered with the people on this, I said: Screaming." Another chain from Ibn 'Abbas, from the Prophet with similar, wording and he said: "From the evil of a vein screaming (with blood)."
