Musnad Abu Ya'la al-Mawsili 9:19

Abu Khaythama narrated to us, Ubayd Allah ibn Musa narrated to us, Abd al-Jabbar ibn al-Abbas narrated to us, from Awn ibn Abi Juhayfah, from his father: That a man slaughtered before the Messenger of Allah, peace and blessings of Allah be upon him, prayed on the Day of Sacrifice. The Messenger of Allah, peace and blessings of Allah be upon him, said, "It does not suffice for you." He said, "O Messenger of Allah, I have a *jadha* (a young sheep)." He said, "It suffices for you, but it will not suffice for anyone after you."
