Musnad Ahmad 180:1

Yahya ibn Sa'id narrated to us, from Yahya ibn Sa'id, from Bashir ibn Yasar, from Abu Burdah ibn Niyar, that he slaughtered before the Prophet, peace and blessings of Allah be upon him, slaughtered. So he ordered him to repeat it. He said: "I do not have anything except a *jadha'ah* (a young lamb/goat)." So he ordered him to slaughter it.
