It was narrated that Al-Bara' said:

"The Messenger of Allah ﷺ addressed us on the day of An-Nahr after the prayer, then he said: 'Whoever prays and offers the sacrifice as we do, his ritual is complete, and whoever offers the sacrifice before the prayer, that is just ordinary meat.' Abu Burdah bin Niyar said: 'O Messenger of Allah ﷺ, by Allah, we offered the sacrifice before I came out to the prayer, because I knew that today is the day of eating and drinking, so I hastened to do it and I ate of it and fed it to my family and neighbors.' The Messenger of Allah ﷺ said: 'That is just a sheep for meat.' He said: 'I have a jadha'ah that is better than two meaty sheep, will that be sufficient (as a sacrifice) for me?' He said: 'Yes, but it will not be sufficient for anyone after you.'"

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ مَنْصُورٍ، عَنِ الشَّعْبِيِّ، عَنِ الْبَرَاءِ، قَالَ خَطَبَنَا رَسُولُ اللَّهِ ﷺ يَوْمَ النَّحْرِ بَعْدَ الصَّلاَةِ ثُمَّ قَالَ " مَنْ صَلَّى صَلاَتَنَا وَنَسَكَ نُسُكَنَا فَقَدْ أَصَابَ النُّسُكَ وَمَنْ نَسَكَ قَبْلَ الصَّلاَةِ فَتِلْكَ شَاةُ لَحْمٍ " . فَقَالَ أَبُو بُرْدَةَ بْنُ نِيَارٍ يَا رَسُولَ اللَّهِ وَاللَّهِ لَقَدْ نَسَكْتُ قَبْلَ أَنْ أَخْرُجَ إِلَى الصَّلاَةِ عَرَفْتُ أَنَّ الْيَوْمَ يَوْمُ أَكْلٍ وَشُرْبٍ فَتَعَجَّلْتُ فَأَكَلْتُ وَأَطْعَمْتُ أَهْلِي وَجِيرَانِي . فَقَالَ رَسُولُ اللَّهِ ﷺ " تِلْكَ شَاةُ لَحْمٍ " . قَالَ فَإِنَّ عِنْدِي جَذَعَةً خَيْرٌ مِنْ شَاتَىْ لَحْمٍ فَهَلْ تُجْزِي عَنِّي قَالَ " نَعَمْ وَلَنْ تُجْزِيَ عَنْ أَحَدٍ بَعْدَكَ " .
