Episode 17: The perfection
the authority of Abu Ya’la Shaddad bin 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.”
It was related by Muslim.
