34. For every previous nation I made rites to shed blood, as a means of closeness to Allah, in the hope they will remember Allah at the time of slaughtering these sacrificial animals, and in gratitude to Allah for the camels, cows and sheep He granted them.

And O Messenger, tell those who are humbly submissive and sincere what will please them.
