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.
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
