(from Al-Bara 'bin Azib) r.a. ; Prophet Muhammad delivered sermon after the prayers worked on the holiday of Nahr and said, "whoever is doing like our prayers and slaughtering (qurban) as we then stabbed him (kurbannya) will be accepted by Allah. And anyone who slaughtered kurbannya before the Id prayer, then stabbed him was not acceptable to God ".
Abu Burdah bin Niyar, uncle Al Bara 'said, "yaa Allah! I have slaughtered my sheep before the Id prayer and I thought that today was a day of eating and drinking, and (was) I want my sheep to be slaughtered first sheep in my house. So I kill it and eat before doing the prayer ".
Prophet Muhammad said, "are you a sheep is slaughtered meat (not stabbing)"
Abu Burdah said, "yaa Allah, I have a young she-goat which is more dear than two my sheep. Is that enough as a stinging in my name?"
Prophet Muhammad said, "yaa, that's enough for you (as a stabbing) but not for anyone else after you".
