Musnad Ahmad 32:1483

'Ali ibn 'Asim narrated to us, Husayn ibn 'Abd al-Rahman informed us, from 'Abd al-Rahman ibn Abi Layla, from Anas ibn Malik, who said: Abu Talha brought two mudds of barley, and he ordered it to be made into food. Then he said to me: "O Anas, go and come to the Messenger of Allah, may Allah bless him and grant him peace, and invite him, and you know what we have." He said: So I came to the Prophet, may Allah bless him and grant him peace, and his companions were with him. I said: "Abu Talha invites you to his food." He stood up and said to the people: "Stand up," and they stood up. I came walking before him until I entered upon Abu Talha and informed him. He said: "You have disgraced us." I said: "I could not refuse the command of the Messenger of Allah, may Allah bless him and grant him peace." When the Prophet, may Allah bless him and grant him peace, reached the door, he said to them: "Sit down," and he entered with ten others. When he sat, the food was brought; he took some and ate, and the people ate with him until they were full. Then he said to them: "Stand up, and let ten enter in your place," until all the people had entered and eaten. He said: I said: "How many were they?" He said: "They were over eighty." He said: And there remained for the people of the house what satisfied them.
