Musnad Abu Ya'la al-Mawsili 141:3

Abu Bakr ibn Abi Shaybah narrated to us, Abdullah ibn Numayr narrated to us, from Sa'd ibn Sa'id, who said: Anas ibn Malik narrated to me, saying: Abu Talhah sent me to the Messenger of Allah (may Allah bless him and grant him peace) to invite him, as he had prepared food for him. I went, and the Messenger of Allah (may Allah bless him and grant him peace) was with the people. He looked at me, and I felt shy, so I said, "Answer Abu Talhah." He said to the people, "Stand up." Abu Talhah said, "O Messenger of Allah, I only prepared a little for you." He said, so the Messenger of Allah (may Allah bless him and grant him peace) wiped over it and invoked blessing upon it. Then he said, "Let in a group of my companions, ten." He said, "Eat." He brought out something from between his fingers, and they ate until they were full and went out. He said, "Let in ten." They ate until they were full and went out. He continued to let in ten men and they would go out, until not one of them remained except that he had entered and eaten until he was full. He said: Then he arranged it, and behold, it was just as it was when they first ate from it.
