On the day of Nahr the Prophet ﷺ offered the prayer and delivered the Khutba and then slaughtered the sacrifice and said, "Anybody who slaughtered (his sacrifice) before the prayer should slaughter another animal in lieu of it, and the one who has not yet slaughtered should slaughter the sacrifice mentioning Allah's name on it."  

صَلَّى النَّبِيُّ ﷺ يَوْمَ النَّحْرِ ثُمَّ خَطَبَ ثُمَّ ذَبَحَ فَقَالَ مَنْ ذَبَحَ قَبْلَ أَنْ يُصَلِّيَ فَلْيَذْبَحْ أُخْرَى مَكَانَهَا وَمَنْ لَمْ يَذْبَحْ فَلْيَذْبَحْ بِاسْمِ اللَّهِ  

That he witnessed the Prophet ﷺ on the Day of Nahr. The Prophet ﷺ offered prayer and then delivered a sermon saying, "Whoever slaughtered his sacrifice before offering prayer, should slaughter another animal in place of the first; and whoever has not yet slaughtered any, should slaughter a sacrifice and mention Allah's Name while doing so."  

أَنَّهُ شَهِدَ النَّبِيَّ ﷺ يَوْمَ النَّحْرِ صَلَّى ثُمَّ خَطَبَ فَقَالَ مَنْ ذَبَحَ قَبْلَ أَنْ يُصَلِّيَ فَلْيَذْبَحْ مَكَانَهَا أُخْرَى وَمَنْ لَمْ يَذْبَحْ فَلْيَذْبَحْ بِاسْمِ اللَّهِ  

I saw Messenger of Allah ﷺ observing ('Id) prayer on the Day of Sacrifice (10th of Dhu'l-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.  

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  

I saw Messenger of Allah ﷺ observing ('Id) prayer on the Day of Sacrifice (10th of Dhu'l-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. (Using translation from Muslim 1960d)   

أَنَّهُ شَهِدَ رَسُولَ اللهِ ﷺ صَلَّى ثُمَّ خَطَبَ فَقَالَ مَنْ كَانَ ذَبَحَ قَبْلَ أَنْ يُصَلِّيَ فَلْيُعِدْ مَكَانَهَا أُخْرَى وَقَالَ مَرَّةً أُخْرَى فَلْيَذْبَحْ وَمَنْ كَانَ لَمْ يَذْبَحْ فَلْيَذْبَحْ بِاسْمِاللهِ  

[Machine] "He (referring to someone) prayed with the Messenger of Allah ﷺ on the day of Eid, and then the Messenger of Allah ﷺ left. Suddenly, he found meat and the sacrifices of Eid, so the Messenger of Allah ﷺ knew that they had been slaughtered before he prayed. So the Messenger of Allah ﷺ said, 'Whoever slaughtered before we prayed, let him slaughter another one in its place. And whoever did not slaughter until we prayed, let him slaughter in the name of Allah.'"  

أَنَّهُ صَلَّى مَعَ رَسُولِ اللهِ ﷺ يَوْمَ أَضْحَى فَانْصَرَفَ رَسُولُ اللهِ ﷺ فَإِذَا هُوَ بِاللَّحْمِ وَذَبَائِحِ الْأَضْحَى فَعَرَفَ رَسُولُ اللهِ ﷺ أَنَّهَا ذُبِحَتْ قَبْلَ أَنْ يُصَلِّيَ فَقَالَ رَسُولُ اللهِ ﷺ مَنْ كَانَ ذَبَحَ قَبْلَ أَنْ نُصَلِّيَ فَلْيَذْبَحْ مَكَانَهَا أُخْرَى وَمَنْ لَمْ يَكُنْ ذَبَحَ حَتَّى صَلَّيْنَا فَلْيَذْبَحْ بِاسْمِ اللهِ  

[Machine] I heard Jundub saying, "I witnessed the Prophet ﷺ and then he delivered a sermon and said, 'Whoever has slaughtered a sacrifice before offering prayers, then let him slaughter again and replace it in its place. And whoever has not slaughtered, then let him slaughter in the name of Allah.'"  

سَمِعْتُ جُنْدُبًا يَقُولُ شَهِدْتُ النَّبِيَّ ﷺ ثُمَّ خَطَبَ فَقَالَ «مَنْ كَانَ ذَبَحَ قَبْلَ أَنْ يُصَلِّيَ فَلْيَذْبَحْ وَلْيُبْدِلْ مَكَانَهَا وَمَنْ لَمْ يَكُنْ ذَبَحَ فَلْيَذْبَحْ بِاسْمِ اللهِ»  

[Machine] The Prophet ﷺ prayed and then said, "Whoever has slaughtered their sacrifice before the prayer, let them slaughter another one in its place. And whoever has not slaughtered, let them slaughter in the name of Allah."  

صَلَّى رَسُولُ اللهِ ﷺ فَقَالَ «مَنْ كَانَ ذَبَحَ أُضْحِيَّتَهُ قَبْلَ الصَّلَاةِ فَلْيَذْبَحْ مَكَانَهَا أُخْرَى وَمَنْ لَمْ يَذْبَحْ فَلْيَذْبَحْ بِاسْمِ اللهْ»
