Musannaf Ibn Abi Shayba 27:69

Abdullah ibn Numayr narrated to us, he said: Sa'd ibn Sa'id narrated to me, he said: Anas ibn Malik narrated to me, he said: Abu Talha sent me to the Messenger of Allah, may Allah bless him and grant him peace, to invite him. He said: So I approached, and the Messenger of Allah, may Allah bless him and grant him peace, was with the people. He said: He looked at me, and I felt shy, so I said: "Answer Abu Talha." He said to the people: "Stand up." Abu Talha said: "O Messenger of Allah, I only prepared a little something for you." He said: So the Messenger of Allah, may Allah bless him and grant him peace, touched it and invoked blessing upon it. Then he said: "Let in a group of my companions, ten." They ate until they were full. He continued to let in ten and let out ten until not one of them remained except that he had entered and eaten until he was full. Then he prepared it, and behold, it was as it was when they ate from it.
