Musnad Ahmad 32:1603

Yunus ibn Muhammad narrated to us, Harb ibn Maymun narrated to us, from an-Nadr ibn Anas, from Anas ibn Malik, who said: Umm Sulaym said: "Go to the Prophet of Allah, may Allah bless him and grant him peace, and say: 'If you would like to have lunch with us, then do so.'" He said: So I came to him and conveyed the message to him. He said: "And who is with me?" I said: "Yes." He said: "Rise." He said: So I came and entered upon Umm Sulaym, and I was bewildered by those who had come with the Messenger of Allah, may Allah bless him and grant him peace. He said: Umm Sulaym said: "What have you done, O Anas?" Then the Messenger of Allah, may Allah bless him and grant him peace, entered right after that. He said: "Do you have any ghee?" She said: "Yes, I had a small skin container of it with some ghee in it." He said: "Bring it." He said: So I brought it to him, and he opened its tie, then said: "In the name of Allah, O Allah, increase the blessing in it." He said: Then he said: "Turn it over." So I turned it over, and the Prophet of Allah, may Allah bless him and grant him peace, squeezed it while mentioning the name of Allah. He said: It began to pour out and flow. Eighty-some men ate from it, and there was some left over. He handed it to Umm Sulaym and said: "Eat and feed your neighbors."
