Narrated by Anas (may Allaah be pleased with him): "The Prophet (peace and blessings of Allaah be upon him) used to break his fast with fresh dates before praying; if fresh dates were not available, he would eat (dried) dates; if dried dates were not available, he would have a few sips of water."
Reported by al-Tirmidhi, 3/79 and others
