Sahih Muslim Book - 35, Hadith - 5070

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى ، أَخْبَرَنَا هُشَيْمٌ ، عَنْ دَاوُدَ ، عَنِ الشَّعْبِيِّ ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ ، أَنَّ خَالَهُ أَبَا بُرْدَةَ بْنَ نِيَارٍ ، ذَبَحَ قَبْلَ أَنْ يَذْبَحَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَقَالَ: يَا رَسُولَ اللهِ ، إِنَّ هَذَا يَوْمٌ اللَّحْمُ فِيهِ مَكْرُوهٌ ، وَإِنِّي عَجَّلْتُ نَسِيكَتِي لِأُطْعِمَ أَهْلِي وَجِيرَانِي وَأَهْلَ دَارِي ، فَقَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَعِدْ نُسُكًا ، فَقَالَ: يَا رَسُولَ اللهِ ، إِنَّ عِنْدِي عَنَاقَ لَبَنٍ هِيَ خَيْرٌ مِنْ شَاتَيْ لَحْمٍ ، فَقَالَ: هِيَ خَيْرُ نَسِيكَتَيْكَ ، وَلاَ تَجْزِي جَذَعَةٌ عَنْ أَحَدٍ بَعْدَكَ.

It was narrated from Al-Bara' bin 'Azib that his maternal uncle Abu Burdah bin Niyar slaughtered (his sacrifice) before the Messenger of Allah (s.a.w) did, and he said: "O Messenger of Allah, this is a day when meat is not desirable so I hastened to offer my sacrifice in order to feed my family and neighbors and household." The Messenger of Allah (s.a.w) said: "Repeat your sacrifice." He said: "O Messenger of Allah, I have a weanling female goat that is better than two sheep for meat." He said: "It is the best of your sacrifice - but no Jadh'ah will suffice for anyone after you."
