CHAPTER: The Fasting Person Who Intentionally Vomits.
Narrated Abu Hurairah: The Prophet صلی اللہ علیہ وسلم said: if one has a sudden attack of vomiting while one is fasting, no atonement is required of him, but if he vomits intentionally he must make atonement.
Narrated Madan bin Talhah: That Abu ad-Darda narrated to him: The Messenger of Allah صلی اللہ علیہ وسلم vomited and broke his fast. Then I met Thawban, the client of the Messenger of Allah صلی اللہ علیہ وسلم, in the mosque in Damascus, I said (to him): Abu al-Darda has told me that the Messenger of Allah صلی اللہ علیہ وسلم vomited and broke his fast. He said: He spoke the truth ; and I poured out water for his ablution صلی اللہ علیہ وسلم.
