He said that the Prophet used to teach them to say when afflicted by fever or any pain, "In the name of God, the Great, I seek refuge in God, the Mighty, from the evil of every vein that bleeds and from the evil of the heat of hell.”
Tirmidhi transmitted it, but said this was a gharib tradition which he knew only among the traditions of Ibrahim b. Isma'il who is declared to be weak in tradition.
Ibn ‘Abbas reported God’s messenger as saying, "No Muslim will visit another and say seven times, ‘I ask God, the Mighty, the Lord of the mighty throne, to cure you’ without his being cured, unless his time has come.”
Abud Darda’ said he heard God’s messenger say, "If one of you has any complaint, or if a brother of his complains of it, he should say, ‘Our Lord God who art in heaven, hallowed be Thy name. Thy command is in the heaven and the earth. As Thy mercy is in the heaven so place Thy mercy in the earth. Forgive us our faults and sins. Thou art the Lord of the good ones. Send down some of Thy mercy and some of Thy healing on this pain’ and it will be cured.”
as saying, “If anyone performs ablution well and pays a sick visit to his brother Muslim seeking his reward from God, he will be removed a distance of sixty years (here kharif is used in another of its meanings) from jahannam.”
