Cupping

It is narrated from Tawus (may Allah have mercy on him): "Indeed the Prophet (peace and blessings be upon him) had himself cupped (that is, had hijamah done) and gave the cupper his wage and payment."
Imam Musaddad recorded it. This hadith is sahih (authentic) on the strength of its supporting narrations, and narrations of the same meaning also exist in Sahih al-Bukhari and Sahih Muslim.

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When I was taken up on the Ascension to the heavens, every company of angels that I passed by said this very thing to me: O Muhammad (peace and blessings be upon him), make cupping (hijamah) binding on yourself."
Imam al-Harith bin Abi Usamah recorded this hadith in his Musnad. Although Muhammad bin Umar al-Waqidi in its chain is not free of criticism, its meaning and text are established on the strength of authentic supporting narrations in other books of hadith.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) was asked about having cupping done, that is, hijamah, and he (peace and blessings be upon him) said: "It is good and beneficial (for health)."
Imam al-Bazzar recorded this hadith in his Musnad; however, the narrator named Yahya bin Hashim in its chain is, according to the hadith scholars, severely weak and matruk (abandoned).

It is narrated from Sayyiduna Ali (may Allah be pleased with him), and he narrates it only from the Prophet (peace and blessings be upon him), that he (peace and blessings be upon him) said: "When the blood of any of you surges (that is, there is an excess of blood), let him shed it (by bloodletting or cupping), even if it be with the broad head of an arrow (mishqas)."
Imam Abu Ya'la al-Mawsili recorded this hadith in his Musnad, and in its chain Muhammad bin al-Qasim al-Asadi is a da'if (weak) narrator.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) had himself cupped (had hijamah done) in the middle of his blessed head, and he (peace and blessings be upon him) named that place (or that procedure) "al-Munqidh" (the rescuer).
Imam Abu Dawud al-Tayalisi recorded it in his Musnad. In its chain Talhah bin Amr is a matruk (abandoned) narrator; however, the basis of having cupping done in the middle of the head is established by other authentic hadith.

It is narrated from Sayyiduna Abdullah bin Ja'far (may Allah be pleased with him): "The Messenger of Allah (peace and blessings be upon him), after being poisoned, had himself cupped on the upper part of his blessed head (that is, had hijamah done)."
Imam Ahmad bin Hanbal recorded this hadith in Musnad Ahmad. In its chain Jabir bin Yazid al-Ju'fi is a da'if (weak) narrator; however, that the Messenger of Allah (peace and blessings be upon him) had cupping done to remove the effect of poison is also established by other authentic hadith.

It is narrated from al-Sari bin Yahya that he heard Muhammad bin Sirin (may Allah have mercy on him) say to a young man who intended to have cupping, that is hijamah, done at the beginning of the month: "Do not have hijamah done at the beginning of the month, for having hijamah in the early days of the month is not beneficial."
Imam Musaddad (may Allah have mercy on him) recorded it in his Musnad.

It is narrated from Sayyiduna Husayn bin Ali (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, on Friday there is a time in which anyone who has cupping done (that is, hijamah) will certainly meet death."
Imam Abu Ya'la recorded this hadith; however, its chain contains narrators such as Jubarah bin al-Mughallis and Yahya bin al-Ala', whom the imams of narrator criticism (al-jarh wa al-ta'dil) declared da'if (weak) and matruk (abandoned), on account of which, according to the hadith scholars, this report is academically unreliable and is judged mawdu' (fabricated).

It is narrated from Sayyiduna Anas (may Allah be pleased with him) that he said: "The Prophet (peace and blessings be upon him), while in the state of ihram, had cupping done (hijamah) because of a pain and discomfort he felt in his blessed head."
The chain of this hadith is sahih (authentic) and all its narrators are thiqat (trustworthy); moreover, Imam Bukhari also recorded it in his Sahih, and it indicates that it is permissible for a person in ihram to have hijamah done in case of an excuse or illness.
