Brief Explanation
Benefits: … What is meant by hastening the slaughter is that the animal should not be slaughtered in such a manner that it is subjected to unnecessary suffering. For example, keeping the animal lying down for a long time, or moving the knife very slowly while cutting the throat. The experts in slaughtering understand this issue well.
