If the sacrificial animal becomes unfit
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، وَعَمْرُو بْنُ عَبْدِ اللَّهِ، قَالُوا حَدَّثَنَا وَكِيعٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ نَاجِيَةَ الْخُزَاعِيِّ، - قَالَ عَمْرٌو فِي حَدِيثِهِ وَكَانَ صَاحِبَ بُدْنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ - قَالَ قُلْتُ يَا رَسُولَ اللَّهِ كَيْفَ أَصْنَعُ بِمَا عَطِبَ مِنَ الْبُدْنِ قَالَ " انْحَرْهُ وَاغْمِسْ نَعْلَهُ فِي دَمِهِ ثُمَّ اضْرِبْ صَفْحَتَهُ وَخَلِّ بَيْنَهُ وَبَيْنَ النَّاسِ فَلْيَأْكُلُوهُ " .
It was narrated that Najiyah Al-Khuza’i – in his narration, ‘Amr (one of the narrators) said that he was the one who looked after the sacrificial animals of the Prophet (ﷺ) – said: “I said: ‘O Messenger of Allah, what should I do with those sacrificial animals that become unfit?’ He said: ‘Slaughter them, dip its sandal in its blood, then place it on its side, and leave them for the people to eat.’”
