Ад-Духан 44:40

مَا خَلَقْنَاهُمَا إِلَّا بِالْحَقِّ وَلَٰكِنَّ أَكْثَرَ‌هُمْ لَا يَعْلَمُونَ "We did not create them but with true purpose, yet most of them do not know. (44:39) " In other words, every wise and thinking person should realise that there is a purpose and objective for creating this universe. The heavens and the earth and everything created in them manifest many realities. Examples are: (1) the manifestation of Divine power; (2) the possibility of the Hereafter. Obviously, the Supreme Creator Who drew out such huge bodies from the realm of non-existence into the realm of existence surely has the power to destroy them and re-create them; (3) the need for retribution (reward/punishment). If there is no retribution in the Hereafter, the very existence of the universe would be rendered purposeless or its purpose would be defeated. The wisdom underlying the creation of the universe is to make it dar-ul-imtihan (the domain of test-n-trial) and the Hereafter is the domain of reward and punishment. Otherwise, the outcome of both good and bad will necessarily be the same. This is far from Divine wisdom, or not in keeping with Divine wisdom; and (4) urging the thinking people to obey Allah and thank Him for having granted man this entire universe or creation as His great blessing
