عَنْ أَبِي يَعْلَى شَدَّادِ بْنِ أَوْسٍ رَضِيَ اللَّهُ عَنْهُ عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ اللهَ كَتَبَ الْإِحْسَانَ عَلَى كُلِّ شَيْءٍ، فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا القِتْلَةَ، وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا الذِّبْحَةَ، وَلْيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ، وَلْيُرِحْ ذَبِيحَتَهُ».
Imepokewa kutoka kwa Abuu Ya'la Shaddad bin Ausi -radhi za Allah ziwe juu yake- amesema: Kutoka kwa Mtume -rehema na amani ziwe juu yake- alisema: "Hakika Mwenyezi Mungu amefaradhisha (kutenda) wema katika kila kitu, hivyo mtakapoua basi uweni vizuri (kwa wema), na mtakapochinja basi chinjeni vizuri, na anowe mmoja wenu kisu chake, na akistareheshe kichinjwa chake".
Abu Ya‘la Shaddād ibn Aws (may Allah be pleased with him) reported that the Messenger of Allah (ﷺ) said: "Indeed, Allah has enjoined Ihsān (kindness/excellence) in all things. So, when you kill, kill with kindness; and when you slaughter, slaughter with kindness. Let one of you sharpen his blade and spare the animal he slaughters suffering."
