عن عبد الله بن عمر رضي الله عنهما قال أمر رسول الله صلى الله عليه وسلم بحد الشفار وأن توارى عن البهائم وقال إذا ذبح أحدكم فليجهز (سنن ابن ماجة، الرقم: 3172)
Hazrat Abdullah bin Umar (radhiyallahu anhuma) reports that Rasulullah (sallallahu alaihi wasallam) commanded that the knives be sharpened (before slaughtering the animal), and that the slaughtering be concealed from the other animals, and he said, “When you slaughter the animal, then slaughter swiftly (so that the least amount of pain is caused to the animal).”
