Salman b. ‘Amir reported God’s messenger as saying, “When one of you breaks his fast he should do so with dates for they provide blessing; but if he cannot get any he should break his fast with water for it is purifying.”
Ahmad, Tirmidhi, Abu Dawud, Ibn Majah and Darimi transmitted it, but only Tirmidhi included “for they provide blessing.”
Anas said that the Prophet used to break his fast before praying with some fresh dates, but if there were no fresh dates he had a few dry dates, and if there were no dry dates he took some mouthfuls* of water.
*Mirqat explains this as three mouthfuls, but 'three' does not occur in the text.
Tirmidhi and Abu Dawud transmitted it, Tirmidhi saying that this is a hasan gharib tradition.
Abu Huraira reported God’s messenger as saying, “When any of you hears the summons to prayer while he has a vessel in his hand he should not lay it down till he finishes his drink.”*
*This is interpreted as referring to the dawn prayer during Ramadan.
