Abu Rafi' narrates: We went to Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) and he was having cupping done after Maghrib. I said: "Why did you not do this during the day?" He said: "Are you telling me to shed my blood while I am fasting?! I heard the Messenger of Allah (peace and blessings be upon him) say: The one who performs cupping and the one who has it done have both broken their fast."

Imam al-Hakim says: I heard Abu Ali al-Hafiz say: I asked Abdan al-Ahwazi: Is it established that the Prophet (peace and blessings be upon him) had cupping done while fasting? He said: I heard Abbas al-Anbari say: I heard Ali bin al-Madini say: The narration of Abu Rafi' from Abu Musa (may Allah be pleased with him) is authentic, that the Prophet (peace and blessings be upon him) said: "The one who performs cupping and the one who has it done have (both) broken their fast." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. In this chapter there are narrations from a group of Companions with reliable chains, the details of which would make this lengthy here.

Imam al-Hakim says: I heard Abu al-Hasan Ahmad bin Muhammad al-Anazi say: I heard Uthman bin Sa'id al-Darimi say: In my view the narration "The one who performs cupping and the one who has it done have broken their fast" is established as authentic because of the hadiths of Thawban and Shaddad bin Aws (may Allah be pleased with them both), and I hold this position. I also found Imam Ahmad bin Hanbal holding this position, and he used to mention that the hadith of Thawban and Shaddad was authentic in his view.
