Chapter: The command to be proficient in slaughtering and killing, and to sharpen the blade

Two are the things which I remember Allah's Messenger (ﷺ) having said: Verily Allah has enjoined goodness to everything; so when you kill, kill in a good way and when you slaughter, slaughter in a good way. So every one of you should sharpen his knife, and let the slaughtered animal die comfortably.

This hadith has been narrated on the authority of Khalid al-Hadhdha' through different chains o transmitters.
