"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 )  

قُلْتُ يَا رَسُولَ اللَّهِ إِنَّا لاَقُو الْعَدُوِّ غَدًا وَلَيْسَ مَعَنَا مُدًى قَالَ مَا أَنْهَرَ الدَّمَ وَذُكِرَ اسْمُ اللَّهِ ﷻ فَكُلْ مَا خَلاَ السِّنَّ وَالظُّفْرَ قَالَ فَأَصَابَ رَسُولُ اللَّهِ ﷺ نَهْبًا فَنَدَّ بَعِيرٌ فَرَمَاهُ رَجُلٌ بِسَهْمٍ فَحَبَسَهُ فَقَالَ إِنَّ لِهَذِهِ النَّعَمِ أَوْ قَالَ الإِبِلِ أَوَابِدَ كَأَوَابِدِ الْوَحْشِ فَمَا غَلَبَكُمْ مِنْهَا فَافْعَلُوا بِهِ هَكَذَا  

"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 and I will tell you about that. As for teeth, they are bones, and as for nails, they are the knives of the Ethiopians,; We acquired some spoils of war including sheep or camels, and a camel ran away, so a man shot an arrow at it an stopped it. The Messenger of Allah 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 )  

قُلْتُ يَا رَسُولَ اللَّهِ إِنَّا لاَقُو الْعَدُوِّ غَدًا وَلَيْسَتْ مَعَنَا مُدًى قَالَ مَا أَنْهَرَ الدَّمَ وَذُكِرَ اسْمُ اللَّهِ ﷻ فَكُلْ لَيْسَ السِّنَّ وَالظُّفْرَ وَسَأُحَدِّثُكُمْ أَمَّا السِّنُّ فَعَظْمٌ وَأَمَّا الظُّفْرُ فَمُدَى الْحَبَشَةِ وَأَصَبْنَا نَهْبَةَ إِبِلٍ أَوْ غَنَمٍ فَنَدَّ مِنْهَا بَعِيرٌ فَرَمَاهُ رَجُلٌ بِسَهْمٍ فَحَبَسَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ لِهَذِهِ الإِبِلِ أَوَابِدَ كَأَوَابِدِ الْوَحْشِ فَإِذَا غَلَبَكُمْ مِنْهَا شَىْءٌ فَافْعَلُوا بِهِ هَكَذَا  

"I heard the Messenger of Allah say: 'Allah, the Mighty and Sublime, has decreed proficiency in all things, so when you kill, kill well, and when you slaughter, slaughter well. Let one of you sharpen his blade and spare suffering to the animal he slaughters" (Sahih)  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ اللَّهَ ﷻ كَتَبَ الإِحْسَانَ عَلَى كُلِّ شَىْءٍ فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا الْقِتْلَةَ وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا الذَّبْحَ وَلْيُحِدَّ أَحَدُكُمْ إِذَا ذَبَحَ شَفْرَتَهُ وَلْيُرِحْ ذَبِيحَتَهُ
