[Machine] "He witnessed the Messenger of Allah ﷺ offering prayer, then he delivered a sermon and said, 'Whoever has slaughtered (their sacrificial animal) before we prayed, let them substitute it with another. And perhaps he said, 'Let them substitute it with another.' And whoever has not done so, let them slaughter (their sacrificial animal) in the name of Allah, the Most High.'"

شَهِدْتُ رَسُولَ اللَّهِ ﷺ صَلَّى يَوْمَ أَضْحًى ثُمَّ خَطَبَ فَقَالَ مَنْ كَانَ ذَبَحَ قَبْلَ أَنْ يُصَلِّيَ فَلْيُعِدْ مَكَانَهَا وَمَنْ لَمْ يَكُنْ ذَبَحَ فَلْيَذْبَحْ بِاسْمِ اللَّهِ
