وَعَنْ أبى يَعْلَى شَدَّادِ بْنِ أَوْسٍ رَضِيَ اللهُ عَنْهُ، عَنْ رَسُولِ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: “إِنَّ اللَّهَ كَتَبَ الإِحْسَانَ عَلَى كُلِّ شئ، فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا اَلْقِتْلَةَ وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا اَلذِّبْحَةَ، وَلْيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ وَلْيُرِحْ ذَبِيحَتَهُ” ((رَوَاهُ مُسْلِمٌ)).
Abu Ya'la Shaddad bin 'Aus (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "Verily Allah has prescribed Ihsan (kindness) for everything. So when you kill, you must make the killing in the best manner; when you slaughter, make your slaughter in the best manner. Let one of you sharpen his knife and give ease to his animal (in order to reduce his pain)." [Muslim].
