Sunan an-Nasa'i 1563

Muhammad ibn ‘Uthman narrated to us; he said: Bahz narrated to us; he said: Shu‘bah narrated to us; he said: Zubayd informed me; he said: I heard al-Sha‘bi say: Al-Bara’ ibn ‘Azib narrated to us beside one of the mosque’s pillars: The Prophet (peace and blessings be upon him) delivered a sermon on the Day of Sacrifice and said: “The first thing we begin with on this day of ours is prayer, then sacrifice. Whoever does that has followed our Sunnah; whoever slaughters before that has only provided meat for his family.” Abu Burdah ibn Niyar had slaughtered and said, “O Messenger of Allah, I have a jadha‘ah that is better than a musinnah.” He said, “Slaughter it, but it will not suffice anyone after you.”
