Narrated Abu Huraira told that when some of the companions of God's messenger remarked to him that truffles are the smallpox of the earth he replied:
“Truffles are a kind of manna, and their juice is a remedy for the evil eye. The 'ajwa dates come from paradise, and they are a remedy for poison.”
Abu Huraira said that he took three, five, or seven truffles, pressed them, put their juice in a bottle and applied it as an eye-lotion to a slavegirl of his who was blear-eyed, and she recovered.
Tirmidhi transmitted it, saying this is a hasan tradition.
Narrated 'Abdallah b. Mas'ud reported God’s messenger as saying:
“Make use of the two remedies: honey and the Qur’an.”
Ibn Majah and Baihaqi, in Shu'ab al-lman, transmitted the two traditions, Baihaqi saying the correct view is that the second goes no farther back than Ibn Mas'ud.
My people sent me to Umm Salama with a bowl of water. Whenever anyone was smitten by the evil eye or anything else he sent her a basin, and she took out some hairs of God’s messenger which she kept in a little silver bell.* She moved it about for him in the water and he drank some of it. I looked into the little bell and saw some red hairs.
Bukhari transmitted it.
* Mirqat, iv, 515, says that although the word means a bell, it may here be used of a small box in the shape of a bell. This is the kind of bell that would be used on a tambourine.
