Jundab al-Bajali reported: I saw Allahs Messenger ﷺ observing (Id) prayer on the Day of Sacrifice (10th of Dhul-Hijja) and then delivering a sermon and he said: He who sacrificed the (animal) before offering (Id) prayer, he should offer again in its stead, and he who did not sacrifice the animal should slaughter it by reciting the name of Allah.
