"The Messenger of Allah said: 'Allah 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.'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ كَتَبَ الإِحْسَانَ عَلَى كُلِّ شَىْءٍ فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا الْقِتْلَةَ وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا الذَّبْحَ وَلْيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ وَلْيُرِحْ ذَبِيحَتَهُ  

“Allah has prescribed Al-Ihsan (proficiency) in all things. So if you kill, then kill well, and if you slaughter, then slaughter well. Let one of you sharpen his blade and spare suffering to the animal he slaughters.” (Using translation from Ibn Mājah 3170)  

عَنْ رَسُولِ اللَّهِ ﷺ «إِنَّ اللَّهَ كَتَبَ الْإِحْسَانَ عَلَى كُلِّ شَيْءٍ فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا الْقِتْلَةَ وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا الذَّبْحَ وَلْيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ وَلْيُرِحْ ذَبِيحَتَهُ»

"There are two things that I memorized from the Messenger of Allah, who said: 'Allah 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) (Using translation from Nasāʾī 4405)  

عَنْ رَسُولِ اللهِ ﷺ «إِنَّ اللهَ كَتَبَ الْإِحْسَانَ عَلَى كُلِّ شَيْءٍ فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا الْقِتْلَةَ وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا الذَّبْحَ لِيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ فَلْيُرِحْ ذَبِيحَتَهُ»

عَنِ النَّبِيِّ ﷺ قَالَ «إِنَّ اللهَ كَتَبَ الْإِحْسَانَ عَلَى كُلِّ شَيْءٍ فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا الْقِتْلَةَ وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا الذَّبْحَ وَلْيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ وَلْيُرِحْ ذَبِيحَتَهُ»  

two are the things which I remember Messenger of Allah ﷺ having said: "Verily Allah has enjoined excellence to everything; so when you kill, kill in a good way and when you slaughter, slaughter in a good way. So every one of you should sharpen his knife, and let the slaughtered animal die comfortably." (Using translation from Muslim 1955a)   

"إِن الله تعالى كَتَبَ الإِحسانَ على كل شَيء، فإِذا قتلتُم فَأحسِنوا القِتْلَةَ، وَإذَا ذبحتم فَأَحْسِنوا الذِّبحةَ، ولْيُحِدَّ أَحدُكم شَفْرتَهُ، وَلْيُرِحْ ذبيحته".

"إِن الله ﷻ مُحْسنٌ يحب الإِحسان فإِذا قتلتم فأَحسنوا القِتْلة وإِذا ذبحتم فأَحسنوا الذَّبْحَ، ولْيُحِدَّ أَحَدُكُم شَفْرَتَه، ثم ليُرِحْ ذَبِيحَتَه".
