Surah Ghafir (The Forgiver) 40 : 79

Explanatory Note

Those who demand miracles are directed to reflect on God's signs that are present everywhere in the world around them. Because of the long familiarity of these, they are often forgotten. Reflection on them, however, is sufficient to give them all the evidence they want. They testify to the fact that God is the Creator of everything in the universe. No one can claim that these have been created by anyone other than God; nor can there be any claim that they existed without being created by God who has planned everything:
It is God who provides livestock for you, some for riding and some for your food. You have other benefits in them too. You can reach on them any destination you wish. On them, as on ships, you are carried. And He shows you His signs: which of God's signs can you still deny? (Verses 79-81)

The creation of livestock is a miracle in the first place, just like the creation of man. To shape and fashion them and to give them life are all miracles which human beings do not even claim. Another miracle is making such livestock subservient to man, when some of them are larger and stronger than man. Yet, "It is God who provides livestockfir you, some for riding and some for your food." To say that such livestock merely exist and we need not concern ourselves with how or why they do is unacceptable. To claim that they are not a clear miracle in relation to man and his ability, or that they do not point to the Creator who originated them and gave them their characteristics, as He did with man, is to make arbitrary claims that run against logic and reason.
