Anas ibn Malik · Fasting (Kitab Al-Siyam)

The Prophet (ﷺ) said: When one of you is fasting, he should break his fast with dates; but if he cannot get any, then (he should break his fast) with water, for water is purifying.

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).

The Prophet (ﷺ) left Medina for Mecca till he reached 'Usfan, He then called for a vessel (of water). It was raised to his mouth to show it to the people, and that was in Ramadan. Ibn 'Abbas used to say: The Prophet (ﷺ) fasted and he broke his fast. He who likes may fast and he who likes may break.

The Prophet (ﷺ) saw a man who had been put in the shade and saw a crowd of people around him (in the course of a journey). He said: Fasting while on journey is not part of righteousness.
