Narrated Ma'qil b. Yasar reported God’s messenger as saying:
“Cupping on Tuesday the 17th of the month is a cure for a year’s illness.”
Harb b. Isma'il al-Kirmani, Ahmad’s companion, transmitted it, but his isnad is worthless. Thus it is stated in al-Muntaqa.
Razin transmitted something to the same effect on the authority of Abu Huraira.
Narrated Nafi' said Ibn ‘Umar told him he was suffering from blood pressure and asked him to bring him a cupper, telling him to be sure to bring a young man and see that he brought neither an old man nor a boy. And Ibn ‘Umar said he had heard God’s messenger say:
“Cupping before food is best; it increases the intelligence, increases the memory and increases the memory of one who has a good memory. He who has himself cupped should choose Thursday, doing it in the name of God most high; but avoid cupping on Friday, Saturday and Sunday. Get yourselves cupped on Monday and Tuesday, but avoid cupping on Wednesday for it is the day when Job was smitten with affliction. Tubercular leprosy and leprosy make their appearance only on Wednesday or Tuesday night.”
Abu Huraira told of hearing God's messenger say, “There should be no taking of omens, but the best type is the good omen."
He was asked what a good omen was and replied, “A good word which one of you hears."
Narrated Abu Kabsha al-Anmari told that God’s messenger had himself cupped on the top of his head because of the poisoned sheep.* Ma'mar said:
I had myself cupped like that in the middle of my head for a reason other than poison and suffered some loss of memory till I was recommended to use Fatihat al-Kitab in the prayer.
Razin transmitted it.
* An attempt was made to poison the Prophet after the conquest of Khaibar in 7 A.H., but when he had taken a mouthful of the poisoned meat he spat it out realizing that it was poisoned.
