“If any of them becomes unfit and you are afraid that it will die, then slaughter it, dip the sandal (tied around its neck) in its blood and place it on its side, but neither you nor any of your companions should eat anything from it.” (Using translation from Ibn Mājah 3105)
أَنَّ رَسُولَ اللهِ ﷺ بَعَثَ مَعَهُ بِبَدَنَةٍ فَقَالَ «إِنْ عَطِبَ مِنْهَا شَيْءٌ فَخَشِتَ مَوْتَهَا فَانْحَرْهَا ثُمَّ اغْمِسْ نَعْلَهَا فِي دَمِهَا ثُمَّ اضْرِبْ بِهَا صَفْحَتَهَا وَلَا تَطْعَمْ مِنْهَا أَنْتَ وَلَا أَحَدٌ مِنْ أَهْلِ رُفْقَتِكَ وَاقْسِمْهَا»
