English translation
2814. It was reported from Shaddād bin Aws who said: "There are two things I heard from the Messenger of Allāh ﷺ: 'Indeed Allāh has ordained Ihsān (beneficence) in everything; so when you kill, then do it in the best manner.'" — Other narrators aside from Muslim said: "So kill in a good manner," — "and when you slaughter, then do it in the best manner, and let one of you sharpen his knife and provide comfort to the animal." (Sahih)
