Hadith about Eating of sahur (sahree)

Holy Prophet Muhammad (peace be upon him and his progeny) has said: Eat your 'sahur' (the morning meal before the start of a fast) even if it is (mere) mouthfuls of water, for the blessings of Allah are upon those who eat the sahur. Tahdheeb al-Akhaam, vol. 4, pg. 198
