Ismael offered himself to be sacrificed. Voluntarily, he told Abraham if “God” commanded the latter to do so, then do so!
The poor animals. Have you seen tears in their eyes? They cry.
They resist when you try to tie them with the rope. They kick back. Do they want to be sacrificed as Ismael did? Do they lay on the ground telling us: “come on, we’re ready. Do what you are commanded to do!”?
