Sayyiduna Thawban (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) was observing a fast, and this was outside of Ramadan. He experienced some discomfort which caused him distress, and as a result, he vomited. Then he vomited again, and called me to perform ablution, so he performed ablution and broke his fast. I asked: "O Messenger of Allah! Is it obligatory to perform ablution after vomiting?" The Noble Prophet (peace and blessings be upon him) said: "If it were obligatory, you would have found its command in the Qur'an." The narrator states: The Noble Prophet (peace and blessings be upon him) fasted the next day, and I heard the Noble Prophet (peace and blessings be upon him) saying: "This is the make-up for the fast I broke yesterday." This narration has only been transmitted from al-Awza'i by 'Atiyyah bin Sakn, and he is a rejected narrator of hadith.
