It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) used to have cupping (hijamah) done on the 17th, 19th and 21st (of the lunar month). This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said to Nafi': "O Nafi'! My blood is agitated, so find me a cupper (hajjam), and if possible let him be gentle; do not bring an old man or a small boy, for I heard the Messenger of Allah (peace and blessings be upon him) saying: 'Cupping (hijamah) on an empty stomach is better; in it there is cure and blessing; it increases the intellect and the memory. So have cupping done with the blessing of Allah on Thursday, and avoid it on Friday, Saturday and Sunday. And have cupping done on Monday and Tuesday, for that is the day on which Allah Almighty relieved Ayyub (peace be upon him) of his trial. Leprosy (baras) and elephantiasis (judham) only appear on Wednesday or on the night of Wednesday, for Ayyub (peace be upon him) was afflicted with his trial on a Wednesday.'" All the narrators of this hadith are trustworthy, except for Uthman bin Ja'far, about whose reliability or criticism I have no knowledge.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever has cupping (hijamah) done on a Wednesday or a Saturday and then is afflicted with leprosy (white patches), let him blame no one but himself."

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that Abu Hind performed cupping (hijamah) on the Prophet (peace and blessings be upon him) at Wajj because of a pain he had, and he (peace and blessings be upon him) said: "If there is any good in the medicines you use, it is in cupping (hijamah)." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Cupping (hijamah) is an excellent medicine: it removes (bad) blood, brightens the eyesight and lightens the back." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
