Ad-Dukhaan 44:42

This World was created for a Wisdom

Here Allah tells us of His justice, and that He is far above mere play, folly and falsehood. This is like the Ayah:

(And We created not the heaven and the earth and all that is between them without purpose! That is the consideration of those who disbelieve! Then woe to those who disbelieve from the Fire!) (38:27)

(Did you think that We had created you in play, and that you would not be brought back to Us So Exalted be Allah, the True King: La ilaha illa Huwa, the Lord of the Supreme Throne!) (23:115-116) Then Allah says:

(Verily, the Day of Judgement is the time appointed for all of them) This is the Day of Resurrection, when Allah will judge between all creatures, and He will punish the disbelievers and reward the believers.

(is the time appointed for all of them) means, He will gather all of them, the first and the last of them.

(The Day when a near relative cannot avail a near relative in aught,) means, no relative will be able to help another relative. This is like the Ayah:

(Then, when the Trumpet is blown, there will be no kinship among them that Day, nor will they ask of one another.) (23:101)

(And no friend will ask a friend (about his condition). Though they shall be made to see one another) (70:10-11) which means, he will not ask his brother about how he is, even though he can see him with his own eyes.

(and no help can they receive,) means, no relative will help another, and no help will come to him from outside.

(Except him on whom Allah has mercy.) means, and nothing will be of any avail that Day except the mercy of Allah towards His creation.

(Verily, He is the All-Mighty, the Most Merciful.) means, he is the Almighty, with immense mercy.

مَا خَلَقْنَاهُمَا إِلَّا بِالْحَقِّ وَلَـٰكِنَّ 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
