He told that when Sa'id b. Mu'adh was shot in the median vein of his arm the Prophet with his own hand cauterized it with a broad arrow head. Afterwards it swelled up and he cauterized it a second time.
Abu Sa'id al-Khudri said that a man came to the Prophet and told him his brother's bowels were loose, so God’s messenger told him to give him honey to drink . He did so and then came and said, “I gave it him to drink but it has only made his bowels more loose.” This he said three times, and when he came a fourth time and was told to give him honey to drink he said, “I have done so, but it has only increased the looseness.” God's messenger replied, “God has spoken the truth and your brother’s bowels have lied.” He then gave him it to drink and he recovered.
Narrated Umm Qais reported God's messenger as saying:
“Why do you compress the uvula in this way? Use this Indian aloes wood, for it contains seven types of remedy, among them being a remedy for pleurisy. It is applied through the nose for a swelling of the uvula and poured into the side of the mouth for pleurisy.”
Narrated Umm Salama told that the Prophet saw in her house a girl with saf’a, i.e. yellowness,* in her face and said:
“Use an invocation for her, for she has been affected by the evil eye.”
(Bukhari and Muslim.)
* Saf’a is explained as a stroke from the devil, or the influence of the evil eye. It may be read suf’a which means blackness, or blackness tinged with red. Sufra normally means yellowness, but it can also mean blackness, and that may be the interpretation it should have here, in which case one should read suf'a.
Jabir told that God’s messenger prohibited invocations, and the family of ‘Amr b. Hazm came and said, “Messenger of God, we had an invocation proved efficacious which we applied for scorpion bite, but you have prohibited invocations.” They submitted it to him and he said, “I see no harm in it. If any of you is able to benefit his brother, let him do so.”
In the pre-Islamic period we used to apply spells, and we asked God’s messenger how he looked upon that. He replied, “Submit your invocations to me. There is no harm in invocations so long as there is no polytheism in them.”
Usama b. Sharik told that when God’s messenger was asked whether they should make use of medical treatment he replied, “Yes servants of God, make use of medical treatment, for God has not made a disease without appointing a remedy for it, with the exception of one disease; viz., old age.”
