Narrator:Anas ibn Mālik
قَالَ أَبُو عَبْدِ اللَّهِ كَتَبَ إِلَىَّ مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا مُعَاذُ بْنُ مُعَاذٍ، حَدَّثَنَا ابْنُ عَوْنٍ، عَنِ الشَّعْبِيِّ، قَالَ قَالَ الْبَرَاءُ بْنُ عَازِبٍ وَكَانَ عِنْدَهُمْ ضَيْفٌ لَهُمْ فَأَمَرَ أَهْلَهُ أَنْ يَذْبَحُوا قَبْلَ أَنْ يَرْجِعَ، لِيَأْكُلَ ضَيْفُهُمْ، فَذَبَحُوا قَبْلَ الصَّلاَةِ، فَذَكَرُوا ذَلِكَ لِلنَّبِيِّ صلى الله عليه وسلم
فَأَمَرَهُ أَنْ يُعِيدَ الذَّبْحَ
Narrated Al-Bara bin Azib that once he had a guest, so he told his family (on the Day of Id-ul-Adha) that they should slaughter the animal for sacrifice before he returned from the ('Id) prayer in order that their guest could take his meal. So his family slaughtered (the animal ) before the prayer. Then they mentioned that event to the Prophet who ordered Al-Bara to slaughter another sacrifice. Al-Bara' said to the Prophet (ﷺ) , "I have a young milch she-goat which is better than two sheep for slaughtering." (The sub-narrator, Ibn 'Aun used to say, "I don't know whether the permission (to slaughter a she-goat as a sacrifice) was especially given to Al-Bara' or if it was in general for all the Muslims.") (See Hadith No. 99, Vol. 2.)
