(Imām Bukhārī narrates): Hamid bin Umar narrated to us from Hammad bin Zaid from Ayyub from Muhammad, that Anas bin Malik, may Allāh be pleased with him, said that

the Messenger of Allāh ﷺ led the prayer on the day of Nahr, then gave the sermon, so he commanded that whoever had slaughtered (the sacrifice) before the prayer should slaughter again. So a man from the Ansar stood up, and he said: O Messenger of Allāh! I have neighbours — either he said that they were very hungry, or he said: they were in great need — and I slaughtered the sacrifice before the prayer, and I have a kid, six months old, which has meat more pleasing than the meat of two goats. So he gave him permission for it (as his sacrifice).
