Musnad Ahmad 1153:1807

Isma'il narrated to us, he said: Sulayman ibn al-Mughirah narrated to me, from Humayd ibn Hilal, he said: 'Aishah said: The family of Abu Bakr sent us a sheep's leg at night. The Messenger of Allah (peace and blessings of Allah be upon him) held it, and it was cut, or he held it and it was cut. The one who was speaking to her said: "Was it without a lamp?" She said: "If we had a lamp, we would have used it as a condiment. Indeed, a month would pass over the family of Muhammad (peace and blessings of Allah be upon him) in which they would not bake bread, nor would they cook a pot."
