Muwatta Imam Malik Book of Hajj, Hadith 154

Yahya related to me from Malik from Hisham ibn Urwa from his father that the man who was in charge of the sacrificial animal of the Messenger of Allah ﷺ said, "Messenger of Allah, what should I do with a sacrificial animal that gets injured?" The Messenger of Allah ﷺ said to him, "Slaughter any sacrificial animal that is injured. Then throw the garlands in its blood, and then give the people a free hand in eating it.

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّ صَاحِبَ، هَدْىِ رَسُولِ اللَّهِ ﷺ قَالَ يَا رَسُولَ اللَّهِ كَيْفَ أَصْنَعُ بِمَا عَطِبَ مِنَ الْهَدْىِ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ " كُلُّ بَدَنَةٍ عَطِبَتْ مِنَ الْهَدْىِ فَانْحَرْهَا ثُمَّ أَلْقِ قِلاَدَتَهَا فِي دَمِهَا ثُمَّ خَلِّ بَيْنَهَا وَبَيْنَ النَّاسِ يَأْكُلُونَهَا " .
