Sayyiduna Thawban (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "The one who gives cupping and the one who gets cupped, their fast is broken." Imam Abu Bakr (may Allah have mercy on him) says that until the end of this chapter, every narration about which I have not said that it is authentic, then that hadith is not according to the condition of our book. Imam Hasan al-Basri (may Allah have mercy on him) did not hear ahadith from Sayyiduna Thawban (may Allah be pleased with him). Imam Abu Bakr (may Allah have mercy on him) says that in my view, this hadith of Sayyiduna Thawban (may Allah be pleased with him) is authentic with this chain.
