An-Nawawy’s Forty Hadiths: (17) Concept of Ihsan
On the authority of Abu Ya’la Shaddad ibn Aws (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said, "Verily Allah has prescribed ihsan (proficiency, perfection) in all things. So if you kill then kill well; and if you slaughter, then slaughter well. Let each one of you sharpen his blade and let him spare suffering to the animal he slaughters." (Muslim)
