Musnad Ahmad 1276:1

Sufyan narrated to us, from al-Zuhri, from Ubayd ibn al-Sabbaq, from Juwayriyah bint al-Harith, who said: The Messenger of Allah (peace and blessings of Allah be upon him) entered upon me one day and said: "Is there any food?" I said: "No, except for a bone that was given to a female servant of ours from the charity (sadaqah)." He (peace and blessings of Allah be upon him) said: "Bring it near, for it has reached its destination."
