Al-Bara' bin 'Azib narrated to us by one of the pillars of the masjid:

"The Prophet ﷺ delivered a Khutbah on the day of An-Nahr and said: 'The first thing we start with on this day of ours is the prayer, then we offer sacrifice. Whoever does that, he has followed our sunnah, but whoever slaughtered (his sacrifice) before the (prayer), that is just meat that he gave to his family. Abu Burdah bin Niyar had slaughtered his sacrifice and he said: 'O Messenger of Allah ﷺ, I have a Jadha'ah that is better than a Musinnah.' He said: 'Slaughter it (as a sacrifice), but that will not be sufficient for anyone else (as a sacrifice) after you.'"

أَخْبَرَنَا مُحَمَّدُ بْنُ عُثْمَانَ، قَالَ حَدَّثَنَا بَهْزٌ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي زُبَيْدٌ، قَالَ سَمِعْتُ الشَّعْبِيَّ، يَقُولُ حَدَّثَنَا الْبَرَاءُ بْنُ عَازِبٍ، عِنْدَ سَارِيَةٍ مِنْ سَوَارِي الْمَسْجِدِ قَالَ خَطَبَ النَّبِيُّ ﷺ يَوْمَ النَّحْرِ فَقَالَ " إِنَّ أَوَّلَ مَا نَبْدَأُ بِهِ فِي يَوْمِنَا هَذَا أَنْ نُصَلِّيَ ثُمَّ نَذْبَحَ فَمَنْ فَعَلَ ذَلِكَ فَقَدْ أَصَابَ سُنَّتَنَا وَمَنْ ذَبَحَ قَبْلَ ذَلِكَ فَإِنَّمَا هُوَ لَحْمٌ يُقَدِّمُهُ لأَهْلِهِ " . فَذَبَحَ أَبُو بُرْدَةَ بْنُ نِيَارٍ فَقَالَ يَا رَسُولَ اللَّهِ عِنْدِي جَذَعَةٌ خَيْرٌ مِنْ مُسِنَّةٍ . قَالَ " اذْبَحْهَا وَلَنْ تُوفِيَ عَنْ أَحَدٍ بَعْدَكَ " .
