An uncle of mine called Abu Burda, slaughtered his sacrifice before the ʿId prayer. So Messenger of Allah ﷺ said to him, "Your (slaughtered) sheep was just mutton (not a sacrifice)." Abu Burda said, "O Allah's Apostle! I have got a domestic kid goat." The Prophet ﷺ said, "Slaughter it (as a sacrifice) but it will not be permissible for anybody other than you" The Prophet ﷺ added, "Whoever slaughtered his sacrifice before the (ʿId) prayer, he only slaughtered for himself, and whoever slaughtered it after the prayer, he offered his sacrifice properly and followed the tradition of the Muslims."  

لَهُ رَسُولُ اللَّهِ ﷺ شَاتُكَ شَاةُ لَحْمٍ فَقَالَ يَا رَسُولَ اللَّهِ إِنَّ عِنْدِي دَاجِنًا جَذَعَةً مِنَ الْمَعَزِ قَالَ اذْبَحْهَا وَلَنْ تَصْلُحَ لِغَيْرِكَ ثُمَّ قَالَ مَنْ ذَبَحَ قَبْلَ الصَّلاَةِ فَإِنَّمَا يَذْبَحُ لِنَفْسِهِ وَمَنْ ذَبَحَ بَعْدَ الصَّلاَةِ فَقَدْ تَمَّ نُسُكُهُ وَأَصَابَ سُنَّةَ الْمُسْلِمِينَ  

Abu Burda slaughtered (the sacrifice) before the (ʿId) prayer whereupon the Prophet ﷺ said to him, "Slaughter another sacrifice instead of that." Abu Burda said, "I have nothing except a Jadha'a." (Shuʿba said: Perhaps Abu Burda also said that Jadha'a was better than an old sheep in his opinion.) The Prophet ﷺ said, "(Never mind), slaughter it to make up for the other one, but it will not be sufficient for anyone else after you."  

لَهُ النَّبِيُّ ﷺ أَبْدِلْهَا قَالَ لَيْسَ عِنْدِي إِلاَّ جَذَعَةٌ قَالَ شُعْبَةُ وَأَحْسِبُهُ قَالَ هِيَ خَيْرٌ مِنْ مُسِنَّةٍ قَالَ اجْعَلْهَا مَكَانَهَا وَلَنْ تَجْزِيَ عَنْ أَحَدٍ بَعْدَكَ وَقَالَ حَاتِمُ بْنُ وَرْدَانَ عَنْ أَيُّوبَ عَنْ مُحَمَّدٍ عَنْ أَنَسٍ عَنِ النَّبِيِّ ﷺ وَقَالَ عَنَاقٌ جَذَعَةٌ
