(الآخِر) كلمة تدل على الترتيب، وهو اسمٌ من أسماء الله الحسنى،...
Shaddād ibn ‘Aws (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Verily, Allah has enjoined kindness upon all things; so when you kill, kill well; and when you slaughter, slaughter well. Let one of you sharpen his blade and spare suffering to the animal he slaughters."
A Muslim is required to make his intention good and have a clear conscience. He is also required to improve his worship and obedience; perfect his work and craft; and act kindly with people, animals, and even inanimate beings. The slaughter of an animal surely causes pain to it. However, its slaughter is necessary for the benefit of human beings. Hence, the Hadīth aims to instill mercy, compassion, and kindness into the soul of the believer so that he will not be heedless of these meanings even if he has a right to slaughter or kill. The Hadīth also draws our attention to the fact that if kindness is required in killing and slaughtering, it is all the more required it in all other acts. Part of kindness is to sharpen the knife and reduce the pain of the animal.
