Sahih Muslim Book 23, Hadith Number 5055.
Abu Huraira reported that Allah’s Messenger (may peace be upon him) went out (of his house) one day or one night, and there he found Abu Bakr and ‘Umar also. He said: What has brought you out of your houses at this hour? They said: Allah’s Messenger, it is hunger. Thereupon he said: By Him in Whose Hand is my life, what has brought you out has brought me out too; get up. They got up along with him and (all of them) came to the house of an Ansari, but he was not at home. When his wife saw him she said: Most welcome, and Allah’s Messenger (may peace be Upon him) said to her: Where is so and so? She said: He has gone to get some fresh water for us. When the Ansari came and he saw Allah’s Messenger (may peace be upon him) and his two Companions, he said: Praise be to Allah, no one has more honourable guests today than I (have). He then went out and brought them a bunch of ripe dates, dry dates and fresh dates, and said: Eat some of them. He then took hold of his long knife (for slaughtering a goat or a sheep). Allah’s Messenger (may peace be upon him) said to him: Beware of killing a milch animal. He slaughtered a sheep for them and after they had eaten of it and of the bunch and drank, and when they had taken their fill and had been fully satisfied with the drink, Allah’s Messenger (may peace be upon him) said to Abu Bakr and Umar: By Him in Whose Hand is my life, you will certainly be questioned about this bounty on the Day of judgment. Hunger brought you out of your house, then you did not return until this bounty came to you.
