Sayyiduna al-Bara' (may Allah be pleased with him) narrates from his maternal uncle Sayyiduna Abu Burdah bin Niyar (may Allah be pleased with him) that he hastily slaughtered a goat before the prayer, then mentioned it to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah, I have hastily slaughtered our child's goat. He (peace and blessings be upon him) said: "Before the prayer?" He said: Yes. He (peace and blessings be upon him) said: "That is a goat for meat." He said: I have a one-year-old goat that is dearer to me than an older one; will it suffice for me? He (peace and blessings be upon him) said: "Yes, but it will not suffice for anyone after you."
