(Imām Bukhārī narrates): Muslim narrated to us, he said: Shu'bah narrated to us from al-Aswad from Jundab, he said: The Prophet ﷺ led the prayer on the day of Nahr, then gave the sermon, then performed the sacrifice, then said: Whoever slaughtered before praying should slaughter another sacrifice in its place, and whoever has not yet slaughtered should slaughter in the name of Allāh.
