Sunan an-Nasai Book 43, Hadith 4409

أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا خَالِدٌ، عَنْ شُعْبَةَ، عَنْ سَعِيدِ بْنِ مَسْرُوقٍ، عَنْ عَبَايَةَ بْنِ رَافِعٍ، عَنْ رَافِعٍ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّا لاَقُو الْعَدُوِّ غَدًا وَلَيْسَ مَعَنَا مُدًى ‏.‏ قَالَ ‏"‏ مَا أَنْهَرَ الدَّمَ وَذُكِرَ اسْمُ اللَّهِ عَزَّ وَجَلَّ فَكُلْ مَا خَلاَ السِّنَّ وَالظُّفْرَ ‏"‏ ‏.‏ قَالَ فَأَصَابَ رَسُولُ اللَّهِ صلى الله عليه وسلم نَهْبًا فَنَدَّ بَعِيرٌ فَرَمَاهُ رَجُلٌ بِسَهْمٍ فَحَبَسَهُ فَقَالَ ‏"‏ إِنَّ لِهَذِهِ النَّعَمِ - أَوْ قَالَ الإِبِلِ - أَوَابِدَ كَأَوَابِدِ الْوَحْشِ فَمَا غَلَبَكُمْ مِنْهَا فَافْعَلُوا بِهِ هَكَذَا ‏"‏ ‏.‏

It was narrated that Rafi said:"I said: 'O Messenger of Allah, we are going to meet the enemy tomorrow, and we do not have any knives.' He said: 'If the blood is shed and the name of Allah is mentioned, then eat, unlike (it is slaughtered) with teeth or nails." Then the Messenger of Allah got some spoils of war and a camel ran away. A man shot and arrow at it and stopped it. He (the Prophet) said; 'Some of these animals - or 'these camels'- 'are untamed like wild animals, so if one of them goes out of your control, do the same."' (Sahih)
