An-Nahl 16:4

Man’s life begins from a humble fluid. But when man grows up, he tries to take a stand in opposition to God. If he were to keep in view the reality of his origin, he would never allow himself to become arrogant in this world. Animals, in particular, cattle, are among the various bounties with which man has been blessed in the present world. These are just like living machines of nature that are engaged in catering to the various requirements of man. Cows consume grass and fodder and convert them into meat and milk for his consumption. Sheep produce wool on their bodies which is used for his clothing. The owner of these animals includes them in his assets and this enhances his prestige. ‘He creates other things beyond your knowledge’ refers to those benefits that are available through sources other than animals. A part of these other sources was available to man even in ancient times. Man has discovered the major part of it in modern times and, for instance, is utilizing machines in place of animals. Man’s innumerable worldly endowments have not been created by him but have been provided for him by God. This shows that the Creator of this world is a kind Creator. Thus it necessarily follows that man should be grateful to his Creator and discharge the obligations due to Him as his Benefactor.
