Muhammad bin Khazim al-Darir محمد بن خازم أبو معاوية الضرير · Fasting (Kitab Al-Siyam)

The Prophet (ﷺ) said: Religion will continue to prevail as long as people hasten to break the fast, because the Jews and the Christians delay doing so.

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).

That Abu ad-Darda' narrated to him: The Messenger of Allah (ﷺ) vomited and broke his fast. Then I met Thawban, the client of the Messenger of Allah (ﷺ), in the mosque in Damascus, I said (to him): Abu al-Darda has told me that the Messenger of Allah (ﷺ) vomited and broke his fast. He said: He spoke the truth ; and I poured out water for his ablution (ﷺ).

The Prophet (ﷺ) said: The day of Arafah, the day of sacrifice, the days of tashriq are (the days of) our festival, O people of Islam. These are the days of eating and drinking.

The Prophet (ﷺ) used to observe i'tikaf during the last ten days of Ramadan. One year he did not observe i'tikaf. When the next year came, he observed i'tikaf for twenty nights (i.e. days).
