Jabir (May Allah be pleased with him) reported:
On the day of the battle of Al-Khandaq (the Trench), we were digging the trench when a very hard boulder came in our way. The Companions went to Messenger of Allah (PBUH) and told him about it. He said, “I will go down the trench to see it.” He stood up and it was noticed that he had tied a stone over his stomach due to intense hunger. We had not tasted anything for three days. He took up a spade and struck the hard rock with it and it turned into sand. I sought his permission to go home, (after reaching home I) said to my wife, “I have seen the Prophet (PBUH) in a state that I am unable to endure. Have you got anything in the house?’
‘She said, “I have a small quantity of barley and a lamb.” I slaughtered the lamb, ground the barley and put the meat in the cooking pot. Then I went to the Prophet (PBUH). In the meantime the flour had been kneaded and the meat in the pot was nearly cooked. I said to him, “O Messenger of Allah, I have some food, will you come along with one or two Companions?’
‘He asked, “How many men should go there?” I told him the number. He said, “It will be better if they are more in number. Tell your wife not to remove the pot from the hearth nor the bread from the oven till I arrive.” Then he said to the Muhajirun and the Ansar:
“Let us go (to eat).” They all rose (and went with him). I went to my wife and said, “Bless you, the Prophet (PBUH), the Muhajirun, the Ansar and the whole company are coming.” She said, “Did he (PBUH) ask you?” I replied in the affirmative.
(When they arrived) Messenger of Allah (PBUH) said to his Companions, “Enter, but do not crowd in.” Then he started breaking up the bread and putting meat on it. He would take from the pot and the oven then would cover them up,
approach his Companions and hand it over to them. He would then go back and uncover the pot and the oven. He continued to break up the bread and put meat on it till all had eaten to their fill and still some of the food remained. Then he said to my wife, “Eat from it, and send it as a present, for the people have been afflicted with severe hunger.” [Al-Bukhari and Muslim].
