Musnad Ahmad 1276:5

'Asim narrated to us, Layth ibn Sa'd narrated to us, Ibn Shihab narrated to me, he said: 'Ubayd ibn al-Sabbaq claims that Juwayriyah, the wife of the Prophet, may God bless him and grant him peace, informed him that the Messenger of God, may God bless him and grant him peace, entered upon her and said: "Is there any food?" She said: "No, by God, we have no food except for a bone from a sheep that was given to my freedwoman from the charity." He, may God bless him and grant him peace, said: "Bring it near, for it has reached its place."
