Shaddad ibn Aws reported: The Messenger of Allah, peace and blessings be upon him, said, “Verily, Allah has prescribed excellence in everything. If you have to kill, kill in the best manner. If you have to slaughter, slaughter in the best manner. Let one of you sharpen his knife, so his animal is spared of suffering.”

عَنْ شَدَّادِ بْنِ أَوْسٍ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ اللَّهَ كَتَبَ الْإِحْسَانَ عَلَى كُلِّ شَيْءٍ فَإِذَا قَتَلْتُمْ فَأَحْسِنُوا الْقِتْلَةَ وَإِذَا ذَبَحْتُمْ فَأَحْسِنُوا الذَّبْحَ وَلْيُحِدَّ أَحَدُكُمْ شَفْرَتَهُ فَلْيُرِحْ ذَبِيحَتَهُ
