The Messenger of Allah (ﷺ) said: Neither vomiting, nor emission, nor cupping breaks the fast of the one who is fasting.
Sunan Abi Dawud Book 14, Hadith 64
← Previous Hadith We would not allow a man who was fasting to get himself cupped due to abomination of hardship.

Sunan Abi Dawud Book 14, Hadith 63 Next Hadith → The Prophet (ﷺ) commanded to apply collyrium mixed with musk at the time of sleep. He said: A man who is fasting should abstain from it.

Abu Dawud said: Yahya b. Ma'in said to me: This tradition about the use of collyrium is munkar (i.e. contradicts the sound traditions on the subject).
