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

[Machine] "The Messenger of Allah ﷺ said, 'This is a sheep of meat.' He then said, 'O Messenger of Allah, I have a portion of goat meat.' He replied, 'Sacrifice it and it won't be suitable for anyone else.'"

رَسُولُ اللهِ ﷺ تِلْكَ شَاةُ لَحْمٍ فَقَالَ يَا رَسُولَ اللهِ إِنَّ عِنْدِي جَذَعَةٌ مِنَ الْمَعْزِ فَقَالَ ضَحِّ بِهَا وَلَا تَصْلُحُ لِغَيْرِكَ

[Machine] He said, "O Messenger of Allah, I have a castrated male goat, should I slaughter it?" He replied, "Slaughter it and it is not permissible for anyone other than you."

أَنَّهُ قَالَ فَقَالَ يَا رَسُولَ اللهِ إِنَّ عِنْدِي دَاجِن جَذَعَةً مِنَ الْمَعْزِ فَقَالَ اذْبَحْهَا وَلَا يَصْلُحُ لِغَيْرِكَ
