Sahih Muslim Book - 35, Hadith - 5072

وحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا عَبْدُ اللهِ بْنُ نُمَيْرٍ (ح) وحَدَّثَنَا ابْنُ نُمَيْرٍ ، حَدَّثَنَا أَبِي ، حَدَّثَنَا زَكَرِيَّا ، عَنْ فِرَاسٍ ، عَنْ عَامِرٍ ، عَنِ الْبَرَاءِ ، قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: مَنْ صَلَّى صَلاَتَنَا ، وَوَجَّهَ قِبْلَتَنَا ، وَنَسَكَ نُسُكَنَا ، فَلاَ يَذْبَحْ حَتَّى يُصَلِّيَ ، فَقَالَ خَالِي: يَا رَسُولَ اللهِ ، قَدْ نَسَكْتُ عَنِ ابْنٍ لِي ، فَقَالَ: ذَاكَ شَيْءٌ عَجَّلْتَهُ لأَهْلِكَ ، فَقَالَ: إِنَّ عِنْدِي شَاةً خَيْرٌ مِنْ شَاتَيْنِ ، قَالَ: ضَحِّ بِهَا ، فَإِنَّهَا خَيْرُ نَسِيْكَتِهِ.

It was narrated that Al-Bara' said: "The Messenger of Allah (s.a.w) said: 'Whoever prays as we do, faces the same Qiblah as we do and offers the same sacrifice as we do, let him not slaughter (his sacrifice) until he has prayed.' My maternal uncle said: 'O Messenger of Allah, I have offered a sacrifice on behalf of a son of mine.' He said: 'That is something that you have hastened to do for your family.' He said: 'I have a sheep that is better than two other sheep.' He said: 'Sacrifice it, for it is the better of the two."'
