What should be done with the sacrificial animal if it gets injured on the way?

Musa b. Salama al-Hudhali reported: I and Sinan b. Salama proceeded (to Mecca to perform Umra. Sinan had a sacrificial camel with him which he was driving. The camel stopped in the way being completely exhausted and this state of it made him (Sinan) helpless. (He thought) if it stops proceeding further how he would be able to take it, along with him and said: I would definitely find out (the religious verdict) about it. I moved on in the morning and as we encamped at al-Batha', (Sinan) said: Come (along with me) to Ibn 'Abbis (Allah be pleased with them) so that we should narrate to him (this incident), and he (Sinan) reported to him the incident of the sacrificial camel. He (Ibn Abbas) said: You have referred (the matter) to the well informed person. (Now listen) Messenger of Allah ﷺ sent sixteen sacrificial camels with a man whom he put in change of them. He set out and came back and said: Messenger of Allah, what should I do with those who are completely exhausted and become powerless to move on, whereupon he said: Slaughter them, and dye their hoofs in their blood, and put them on the sides of their humps, but neither you nor anyone among those who are with you must eat any part of them.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا عَبْدُ الْوَارِثِ بْنُ سَعِيدٍ، عَنْ أَبِي التَّيَّاحِ الضُّبَعِيِّ، حَدَّثَنِي مُوسَى بْنُ سَلَمَةَ الْهُذَلِيُّ، قَالَ انْطَلَقْتُ أَنَا وَسِنَانُ بْنُ سَلَمَةَ، مُعْتَمِرَيْنِ قَالَ وَانْطَلَقَ سِنَانٌ مَعَهُ بِبَدَنَةٍ يَسُوقُهَا فَأَزْحَفَتْ عَلَيْهِ بِالطَّرِيقِ فَعَيِيَ بِشَأْنِهَا إِنْ هِيَ أُبْدِعَتْ كَيْفَ يَأْتِي بِهَا . فَقَالَ لَئِنْ قَدِمْتُ الْبَلَدَ لأَسْتَحْفِيَنَّ عَنْ ذَلِكَ . قَالَ فَأَضْحَيْتُ فَلَمَّا نَزَلْنَا الْبَطْحَاءَ قَالَ انْطَلِقْ إِلَى ابْنِ عَبَّاسٍ نَتَحَدَّثْ إِلَيْهِ . قَالَ فَذَكَرَ لَهُ شَأْنَ بَدَنَتِهِ . فَقَالَ عَلَى الْخَبِيرِ سَقَطْتَ بَعَثَ رَسُولُ اللَّهِ ﷺ بِسِتَّ عَشْرَةَ بَدَنَةً مَعَ رَجُلٍ وَأَمَّرَهُ فِيهَا - قَالَ - فَمَضَى ثُمَّ رَجَعَ فَقَالَ يَا رَسُولَ اللَّهِ كَيْفَ أَصْنَعُ بِمَا أُبْدِعَ عَلَىَّ مِنْهَا قَالَ " انْحَرْهَا ثُمَّ اصْبُغْ نَعْلَيْهَا فِي دَمِهَا ثُمَّ اجْعَلْهُ عَلَى صَفْحَتِهَا وَلاَ تَأْكُلْ مِنْهَا أَنْتَ وَلاَ أَحَدٌ مِنْ أَهْلِ رُفْقَتِكَ " .

Ibn Abbas (Allah be pleased with them) reported that Messenger of Allah ﷺ sent eighteen sacrificial camels with a person. The rest of the hadith is the same, and the first part (of the above-mentioned hadith) is not mentioned.

وَحَدَّثَنَاهُ يَحْيَى بْنُ يَحْيَى، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَعَلِيُّ بْنُ حُجْرٍ قَالَ يَحْيَى أَخْبَرَنَا وَقَالَ الآخَرَانِ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ، عَنْ أَبِي التَّيَّاحِ، عَنْ مُوسَى بْنِ سَلَمَةَ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ بِثَمَانَ عَشْرَةَ بَدَنَةً مَعَ رَجُلٍ . ثُمَّ ذَكَرَ بِمِثْلِ حَدِيثِ عَبْدِ الْوَارِثِ وَلَمْ يَذْكُرْ أَوَّلَ الْحَدِيثِ .
