The same narration is also reported by Imam Sufyan bin Sa'id Thawri, may Allah have mercy on him, and Imam Sufyan Thawri, may Allah have mercy on him, was among those scholars of his time whom no other religious scholar could match in precise memorization. He narrates from Zaid bin Aslam, and he from one of his companions, who narrates from a companion of the Messenger of Allah, peace and blessings be upon him, that the Prophet, peace and blessings be upon him, said: "Whoever vomits, his fast is not broken; whoever has a wet dream, his fast is not broken; and whoever undergoes cupping, his fast is not broken." Imam Abu Bakr, may Allah have mercy on him, says that if this narration had been reported from Abu Sa'id, may Allah be pleased with him, through the chain of 'Ata bin Yasar, then Imam Sufyan Thawri would have clarified both of these individuals and would not have remained silent about their names. He would not have said in this manner that he narrates from one of his companions, and he from a companion. This unknown method of narration is only adopted when the narrator is not well-known (whereas the fame of Imam 'Ata and Sayyiduna Abu Sa'id al-Khudri, may Allah be pleased with him, is beyond introduction).
