Sayyiduna Bara’ bin Azib (may Allah be pleased with both of them) narrates that the Noble Prophet (peace and blessings of Allah be upon him) said: No one should slaughter an animal (for sacrifice) before the (Eid) prayer. Sayyiduna Bara’ (may Allah be pleased with both of them) says: My uncle Abu Burdah bin Niyar stood up and said: O Messenger of Allah! On this day there is a lot of meat, I have already slaughtered my sacrifice so that my neighbors and family may eat from it. I have a one-year-old goat, which is better than two goats with more meat. Should I slaughter it (as a sacrifice)? He said: Yes! But after you, it will not suffice for anyone, and it is better for you than two sacrifices.
