Examine the eyes and ears of an animal before sacrificing them.

The Prophet Muhammad taught us to be mindful and responsible when it comes to sacrificing animals. He commanded us to examine the eyes and ears of the animal before we sacrifice it, so that we can ensure that it is healthy enough for sacrifice. This teaches us that we should always be mindful of our actions, especially when dealing with animals, as they are living creatures too. We should also take responsibility for our actions and make sure that whatever we do is done in a humane way.
