The Messenger of Allah ﷺ vomited and broke his fast.Madan bin Abu Talha said, "I met Thawban, the freed slave of the Messenger of Allah ﷺ, in the mosque of Damascus and said to him, 'Abu Darda told me that the Prophet ﷺ vomited and broke his fast.'"Thawban replied, "He spoke the truth, and I myself poured the water for his ablution."
إن رسول الله ﷺ قاء فأفطر، قال معدان ابن أبي طلحة فلقيت ثوبان مولى رسول الله ﷺ في مسجد دمشق فقلت: إن أبا الدرداء حدثني أن النبي ﷺ قاء فأفطر، قال: صدق، وأنا صببت له وضوءه.
Abu Dawud (2381) reported it, and this is his wording, and Tirmidhi (87) also reported it, both of them from Abdul-Warith, from Husayn bin Zakwan the teacher, from Yahya bin Abu Kathir, who said Abdul-Rahman bin Amr Uzai told me, from Yaish bin Walid bin Hisham, that his father told him, who said Madan bin Abu Talha told me, that Abu Darda told him, and he then related the hadith. Its chain of transmission is sahih. Tirmidhi's wording is, "He vomited and performed wudu." Shaykh Ahmad Shakir noted that in some copies of Tirmidhi's book it reads, "He vomited, broke his fast, and performed wudu."Imam Ahmad reported it (27502), and Ibn Khuzayma graded it sahih (1957), both of them through the route of Husayn (that is, Ibn Zakwan the teacher) with his chain of transmission, with the wording, "He vomited and broke his fast." So whoever understood from Thawban's statement, "He vomited, so he broke his fast, so I got his wudu water ready for him," said, "He vomited, broke his fast, and performed wudu."As for his statement "he vomited and broke his fast," it requires interpretation to mean that he deliberately induced vomiting, because vomiting does not break the fast of one who is fasting.Tirmidhi said, Ishaq bin Mansur said, "Madan bin Talha." Then he said, "But Ibn Abu Talha is more correct." He said, "Husayn the teacher transmitted this hadith excellently, and the hadith of Husayn is the most sahih thing on this topic. Mamar also transmitted this hadith from Yahya bin Abu Kathir, but he erred in it, saying, 'from Yaish bin Walid, from Khalid bin Madan, from Abu Darda,' without mentioning Uzai in it, and he said 'from Khalid bin Madan,' when it is really Madan bin Abu Talha." End of Tirmidhi's statement.I say, this narration of Mamar's was transmitted by Imam Ahmad (27537) from Abdul-Razzaq, who said Mamar told us, from Yahya bin Abu Kathir, from Yaish bin Walid, from Khalid bin Madan, from Abu Darda, who said, "The Messenger of Allah ﷺ induced vomiting, so he broke his fast, and water was brought to him, so he performed wudu."Shaykh Ahmad Shakir says in his commentary on Tirmidhi, "We do not agree with Tirmidhi in his claim that Mamar made an error here. In our view, this is simply another chain of transmission for the hadith. Khalid bin Madan is a well-known and reliable successor, who died at the beginning of the second century. He narrated from many companions, including Muawiya, though there is disagreement over whether he actually heard from Abu Darda. Yaish bin Walid is likewise a reliable successor, and he narrated from Muawiya. Muawiya died in the year 59 or 60 AH. Since Yaish bin Walid and Khalid bin Madan were both from the people of Syria, it is not unlikely that one of them narrated from the other. Mamar was a reliable and precise memorizer of hadith, so he should not be charged with error without solid grounds."So if this hadith is sahih, then it requires no reinterpretation.As for whether vomiting and nosebleeds invalidate wudu, Tirmidhi said, "Some scholars held this view, among them Sufyan Thawri, Ibn Mubarak, Ahmad, and Ishaq. Malik and Shafii said there is no wudu required for vomiting or nosebleed." End.
