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.
Abu Huraira said that God’s messenger forbade uninterrupted fasting, and when a man said, “You fast uninterruptedly, messenger of God,” he replied, “Which of you is like me? During the night my Lord gives me food and drink.”
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.
‘Umar reported God’s messenger as saying, “When the night approaches on this side and the day retreats on that side and the sun sets, he who fasts has reached the time to break it.”
