20.That is: the creation of the heavens with their infinite stars, wonderful Milky Ways, magnificent plants and grand solar systems and making them follow an orderly and disciplined performance is not an easy task. But when the creation of this astounding universe was an easy task for Allah, then why the task of reviving man should be at all difficult for Him? Why such an obvious thing is not understood by your intellect?

21. The expanse of the universe is so great and some of the stars are so far away from us that it takes a number of light years for their light to reach our earth.

22. That is: He did not merely create the matter or the nebular of the heaven and left it at that, but He also created from it a magnificent universe, effected co-ordination among all the members, and organized it in such a way that the heavens appear to be a beautifully decorated gathering, which invites every thinking man to ponder seriously over these matters.

23.To connect the occurrence of day and night with the sky is on account of the fact that man sees the signs of day and night in the sky only.

24. It does not mean that first the heaven was created and thereafter the earth was brought into being. It means that in addition to heaven, the earth was also created and spread. Both the magnificence of the heaven and the blessings of the earth are worth reflecting upon.

25. This beneficial and wise arrangement of the earth points to a splendid planning or scheme. The Quran explains this planning or scheme as that of life after death and the facing of the consequences of man’s deeds.

26. In other words the occurring of the Doomsday which is the biggest event of the universe.

27. Everything a man does leaves its impressions on his mind. For this reason a man is able to remember the events of very remote past of his life. This is a proof that man’s brain is itself preparing a record of his deeds. On the Day of Reckoning his memory will be so sharp that all the past impressions of what he did in his life will come out before his eyes, i.e. he will remember everything perfectly.

28. That is: Instead of remaining a loyal slave to Allah he would have adopted the line of rejection and rebellion. Earlier the example of the rebellion of Pharaoh has been given.

29. That is: This man would have made this world as his goal and would have preferred the pleasure and comforts of this world to the pleasures of the next.

30. This refers to the man who used to tremble in his worldly life from the thought of appearing before Allah to account for his deeds. It goes without saying that such a man would have led very pious and virtuous life as a loyal slave of Allah.

31. It means that the Messenger of Allah has not been sent to declare the time of the occurrence of the Doomsday. He has been sent to warn the people. The Doomsday will occur at its appointed time, in the same way in which a man’s death occurs inevitably and the time of its occurring is not known beforehand.

32. Now they are showing impatience for the Doomsday, but when it will actually occur, they will feel that it has come too soon, and the time they had at their disposal in the world was too short. Time is a relative thing. Minutes appear too short in comparison with hours, and hours and days too short in comparison with days and months, respectively, and so on. In the Hereafter the present values of time and space will change, and at that time the Doomsday will be equal to 1000 years of this world. At that time the life span of man in this world will look terribly short, and then man will realise that he had foolishly wasted his precious time. How he would wish that he had spent this invaluable time in making preparation for the life of the Hereafter!
