Sayyiduna Shaddad bin Aws (may Allah be pleased with him) narrates: Once, on the eighteenth of Ramadan, I was walking with the Prophet Muhammad (peace and blessings be upon him). During this time, the Prophet (peace and blessings be upon him) turned his attention and saw a man who was getting cupped. The Prophet (peace and blessings be upon him) said: The one who performs cupping and the one who gets cupped, their fast is broken. (Imam Ibn Hibban, may Allah have mercy on him, says:): Abu Qilabah also heard this narration from Abu Asma from Sayyiduna Thawban (may Allah be pleased with him), and he also heard this narration from Abu Ash'ath from Abu Asma from Sayyiduna Shaddad bin Aws (may Allah be pleased with him), so both chains are preserved. Shayban bin Abdur Rahman combined both chains of this narration transmitted from Yahya bin Abu Kathir, which is narrated from Abu Qilabah from Abu Asma from Sayyiduna Thawban (may Allah be pleased with him), and from Abu Ash'ath from Abu Asma from Sayyiduna Shaddad bin Aws (may Allah be pleased with him).
