وَعَنْ شَدَّادِ بْنِ أَوْسٍ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ إِنَّ اَللَّهَ كَتَبَ اَلْإِحْسَانَ عَلَى كُلِّ شَيْءٍ, فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا اَلْقِتْلَةَ, وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا اَلذِّبْحَةَ, وَلْيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ, وَلْيُرِحْ (1756) ذَبِيحَتَهُ } رَوَاهُ مُسْلِمٌ (1757) .
Shaddad bin Aus (RAA) narrated that the Messenger of Allah (ﷺ) said: "Verily, Allah has prescribed proficiency in all things. Thus, if you kill, kill in the least painful manner you can; and when you slaughter an animal, do it in the best possible way; and any of you should sharpen his blade so that the animal may be spared from the suffering of the slaughtering."
