Hazrat Bara bin Azib (may Allah be pleased with him) narrated that my uncle Abu Burdah (may Allah be pleased with him) had performed the sacrifice before the Eid prayer. The Prophet (peace and blessings of Allah be upon him) said to him, "Your goat is only a goat for meat." He submitted, "O Messenger of Allah! I have a kid goat that is less than a year old." The Prophet (peace and blessings of Allah be upon him) said, "You may slaughter it, but after you, it will not be permissible for anyone else (to sacrifice such a goat)." Then he said, "Whoever performs the sacrifice before the Eid prayer, he only slaughters an animal for his own food, and whoever performs the sacrifice after the Eid prayer, his sacrifice is complete and he attains the Sunnah of the Muslims."
