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  

I witnessed the Prophet ﷺ offering the ʿId prayer (and after finishing it) he delivered a sermon and said, "Whoever has slaughtered his sacrifice (before the prayer) should make up for it (i.e. slaughter another animal) and whoever has not slaughtered his sacrifice yet, should slaughter it by mentioning Allah's Name over it."  

شَهِدْتُ النَّبِيَّ ﷺ صَلَّى يَوْمَ عِيدٍ ثُمَّ خَطَبَ ثُمَّ قَالَ مَنْ ذَبَحَ فَلْيُبَدِّلْ مَكَانَهَا وَمَنْ لَمْ يَكُنْ ذَبَحَ 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] I heard Jundub ibn Sufyan saying, "I witnessed with the Prophet ﷺ the Day of Sacrifice (Eid al-Adha), then he delivered a sermon and said, 'Whoever slaughtered before we prayed, let him count his sacrifice. And whoever did not slaughter, let him slaughter in the name of Allah ﷻ.'"  

سَمِعْتُ جُنْدُبَ بْنَ سُفْيَانَ يَقُولُ شَهِدْتُ مَعَ النَّبِيِّ ﷺ الْعِيدَ يَوْمَ النَّحْرِ ثُمَّ خَطَبَ فَقَالَ مَنْ ذَبَحَ قَبْلَ أَنْ نُصَلِّيَ فَلْيُعِدْ أُضْحِيَّتَهُ وَمَنْ لَمْ يَذْبَحْ فَلْيَذْبَحْ عَلَى اسْمِ اللهِ ﷻ  

[Machine] I witnessed the Eid sacrifice with the Prophet ﷺ , and he saw some people who had slaughtered their animals before the prayer. He said, "Whoever has already slaughtered their animal before the prayer should repeat the sacrifice, and whoever has not yet slaughtered should do so in the name of Allah."  

شَهِدْتُ الْأَضْحَى مَعَ النَّبِيِّ ﷺ فَرَأَى نَاسًا قَدْ ذَبَحُوا قَبْلَ الصَّلَاةِ فَقَالَ «مَنْ كَانَ ذَبَحَ قَبْلَ الصَّلَاةِ فَلْيُعِدِ الذَّبْحَ وَمَنْ لَمْ يَكُنْ ذَبَحَ فَلْيَذْبَحْ عَلَى اسْمِ اللهِ»  

"مَنْ كان ذبَحَ أُضْحِيَتهُ قبْل أَنْ يُصَلِّيَ، فليَذْبَحْ مَكانَها أُخْرَى، وَمَنْ لمْ يَكُنْ ذبَحَ فليَذْبَحْ بِاسْمِ اللهِ".
