Al-Hajj · 22:36

36. And I have made the camels which are taken to the House amongst the sacred signs and symbols of the religion. In them are worldly and religious benefits for you, so say “in the name of Allah” when slaughtering them, after their feet have been lined up whilst standing and one of their feet has been tied so that they do not flee. Then when they fall on their sides after being slaughtered, eat of them, O those who are sacrificing, and give of them to the pauper who desists from begging and the pauper who comes forward to be granted a share of them. Just as I made them submissive to you so that you carry loads on them and ride them, I have also made them submissive to you so they are led to the place you slaughter them in, as a means of closeness to Allah, so that you are grateful to Allah for the blessing of making them submissive to you.
