It was narrated that Al-Bara bin 'Azib said:

"The Messenger of Allah addressed us on the Day of Sacrifice and said: 'whoever prays as we pray nand offers the sacrtifice as we do, has done the rituals properly. Whoever offered the sacrifice before the prayer, that is just a sheep for meat." Abu Burdah said: 'O Messengers of Allah, by Allah, I offered my sacrifice before I went out to pray. I knew that this day is a day of eating and drinking, so I hastened to eat and to feed my family and my neighbors.' The Messenger of Allah said: 'The Messenger of Allah said; 'That was just a sheep for meat.' He said: 'I have a Jadh'ah she-goat that is better than two sheep for meat; will it suffice for me (as a sacrifice)?' He said: 'Yes, but it will never suff8ice for anyone after you."'

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ مَنْصُورٍ، عَنِ الشَّعْبِيِّ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، 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 يَا رَسُولَ اللَّهِ وَاللَّهِ لَقَدْ نَسَكْتُ قَبْلَ أَنْ أَخْرُجَ إِلَى الصَّلاَةِ وَعَرَفْتُ أَنَّ الْيَوْمَ يَوْمَ أَكْلٍ وَشُرْبٍ فَتَعَجَّلْتُ فَأَكَلْتُ وَأَطْعَمْتُ أَهْلِي وَجِيرَانِي . فَقَالَ رَسُولُ اللَّهِ ﷺ " تِلْكَ شَاةُ لَحْمٍ " . قَالَ فَإِنَّ عِنْدِي عَنَاقًا جَذَعَةً خَيْرٌ مِنْ شَاتَىْ لَحْمٍ فَهَلْ تُجْزِئُ عَنِّي قَالَ " نَعَمْ وَلَنْ تَجْزِيَ عَنْ أَحَدٍ بَعْدَكَ " .
