Sayyiduna Thawban (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) was observing a fast, and this was not one of the Ramadan fasts. He experienced some discomfort, which became distressing for him, and then he vomited. After that, he asked for water to perform ablution, performed ablution, and broke his fast. I asked: O Messenger of Allah! Is it obligatory to perform ablution after vomiting? The Prophet (peace and blessings be upon him) replied: "If it were obligatory, you would have found it in the Qur'an." The narrator states: After that, the Prophet (peace and blessings be upon him) fasted the next day, and I heard him say: "This is in compensation for the fast I broke yesterday." The narrator of this narration, Utbah bin Sakan, is abandoned in hadith.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever vomits deliberately, then making up (the fast) is obligatory upon him, and whoever is overcome by vomiting, then making up (the fast) is not obligatory upon him." All the narrators of this narration are trustworthy.

This narration is also transmitted with another chain of transmission.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings be upon him): "When a fasting person vomits a mouthful involuntarily, breaking the fast is not obligatory upon him, nor is making up the fast obligatory upon him. But if he vomits deliberately, then making up the fast is obligatory upon him." The narrator of this narration, Yahya bin Sa'id, is not reliable.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "Whoever vomits involuntarily with a mouthful, let him complete his fast; there is no making up (qada) upon him. And whoever vomits deliberately, let him make up (the fast)."
