She said that when the Prophet had a complaint he would blow on himself, ejecting saliva, reciting the Mu'awwidhat (See n. 1, p, 197.), and wipe himself with his hand. She said, “When he suffered from the pain of which he died, I would blow on him ejecting saliva and recite the Mu'awwidhat as he did, and would take the Prophet’s hand to wipe him.”
(Bukhari and Muslim.)
In a version by Muslim she said, “When one of his family was ill he would blow on him ejecting saliva and recite the Mu'awwidhat.
She said that when a person complained of some trouble, or if he had a sore or a wound, the Prophet would say while pointing with his finger, “In the name of God. It is the soil of our land with the spittle of one of us (the suggestion is that the Prophet took some earth on his finger and spat on it), that our sick one may be healed by our Lord’s permission.”
Uthman b. Abul ‘As said he complained to God’s messenger of a pain he had in his body, and he told him to put his hand on the part of his body which was sore and say three times “In the name of God,” and seven times, “I seek refuge in God’s might and power from the evil of what I am experiencing and trying to avert.” He said he did so, and God removed his trouble.
When one of us had a complaint God’s messenger wiped him with his right hand and then said, “Remove the harm, Lord of men, and give healing. Thou art the Healer. There is no healing but Thine, a healing which leaves no illness behind.”
