[Pooya/Ali Commentary 55:5] The precise laws, made by Allah, governing the universe, bear witness to Allah's wisdom and justice and also to His favours to His creatures. Man relies upon the laws operating the universe and, without fear of any arbitrary change, directs his activities in the light of knowledge he has acquired about its working. Although Allah has absolute power over all things yet it is His justice, a consequence of His beneficence (rahmaniyyat) that He makes no arbitrary changes in His laws, otherwise there would be chaos and disorder in the whole universe. This fact of order and harmony prevailing in the working of universe was made known to man at a time when only conjectures and superstitions prevailed. It gave stimulus and sense of direction to man to observe, contemplate and find out the laws operating the creation. Refer to the commentary of Jathiyah: 3 to 11.
