Jabir b. 'Abdullah reported

When the ditch was dug, I saw Allah's Messenger (may peace he upon him) feeling very hungry. I came to my wife and said to her: Is there anything with you? I have seen Allah's Messenger (ﷺ) feeling extremely hungry. She brought out a bag of provisions which contained a sa', of barley. We had also with us a lamb. I slaughtered it. She ground the flour. She finished (this work) along with me. I cut it into pieces and put it in the earthen pot and then returned to Allah's Messenger (ﷺ) (for inviting him). She said: Do not humiliate me in the presence of Allah's Messenger (ﷺ) and those who are with him. When I came to him I whispered to him saying: Allah's Messenger, we have slaughtered a lamb for you and she has ground a sa' of barley which we had with us. So you come along with a group of people with you. Thereupon Allah's Messenger (ﷺ) said loudly: O people of the ditch, Jabir has arranged a feast for you, so (come along). Allah's Messenger (ﷺ) said: Do not remove your earthen pot from the hearth and do not bake the bread from the kneaded flour until I come. So I came and Allah's Messenger (ﷺ) came and he was ahead of the people; and I came to my wife and she said (to me): You will be humbled. I said: I did what you had asked me to do. She (his wife) said: I brought out the kneaded flour and Allah's Messenger (ﷺ) put some saliva of his in that and blessed It. He then put saliva in the earthen pot and blessed it and then said. Call another baker who can bake with you. and bring out the soup from it, but do not remove it from the hearth, and the guests were one thousand. (Jabir said): I take an oath by Allah that all of them ate (the food to their fill) until they left it and went away and our earthen pot was brimming over as before, and so was the case with our flour, or as Dahhak (another narrator) said: It (the flour) was in the same condition and loaves had been prepared from that.
