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.
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.”
Hafsa reported God’s messenger as saying, “He who does not before dawn express his intention of fasting is not credited with it.”
Tirmidhi, Abu Dawud, Nasa’i and Darimi transmitted it. Abu Dawud said that Ma'mar, az-Zubaidi, Ibn ‘Uyaina and Yunus al-Aili, all of whom got it on Zuhri’s authority, traced it no farther back than Hafsa.
