Narrated Al-Bara' bin `Azib: An uncle of mine called Abu Burda, slaughtered his sacrifice before the `Id prayer. So Allah's Apostle said to him, Your (slaughtered) sheep was just mutton (not a sacrifice). Abu Burda said, O Allah's Apostle! I have got a domestic kid. The Prophet said, Slaughter it (as a sacrifice) but it will not be permissible for anybody other than you The Prophet added, Whoever slaughtered his sacrifice before the (`Id) prayer, he only slaughtered for himself, and whoever slaughtered it after the prayer, he offered his sacrifice properly and followed the tradition of the Muslims.
