﴿ يَٰٓأَيُّهَا ٱلنَّاسُ إِن كُنتُمْ فِى رَيْبٍۢ مِّنَ ٱلْبَعْثِ فَإِنَّا خَلَقْنَٰكُم مِّن تُرَابٍۢ ثُمَّ مِن نُّطْفَةٍۢ ثُمَّ مِنْ عَلَقَةٍۢ ثُمَّ مِن مُّضْغَةٍۢ مُّخَلَّقَةٍۢ وَغَيْرِ مُخَلَّقَةٍۢ لِّنُبَيِّنَ لَكُمْ ۚ وَنُقِرُّ فِى ٱلْأَرْحَامِ مَا نَشَآءُ إِلَىٰٓ أَجَلٍۢ مُّسَمًّۭى ثُمَّ نُخْرِجُكُمْ طِفْلًۭا ثُمَّ لِتَبْلُغُوٓا۟ أَشُدَّكُمْ ۖ وَمِنكُم مَّن يُتَوَفَّىٰ وَمِنكُم مَّن يُرَدُّ إِلَىٰٓ أَرْذَلِ ٱلْعُمُرِ لِكَيْلَا يَعْلَمَ مِنۢ بَعْدِ عِلْمٍۢ شَيْـًۭٔا ۚ وَتَرَى ٱلْأَرْضَ هَامِدَةًۭ فَإِذَآ أَنزَلْنَا عَلَيْهَا ٱلْمَآءَ ٱهْتَزَّتْ وَرَبَتْ وَأَنۢبَتَتْ مِن كُلِّ زَوْجٍۭ بَهِيجٍۢ ﴾

“O MEN! If you are in doubt as to the [truth of] resurrection, [remember that,] verily, We have created [every one of] you out of dust, then out of a drop of sperm, then out of a germ-cell, then out of an embryonic lump complete [in itself] and yet incom­plete so that We might make [your origin] clear unto you. And whatever We will [to be born] We cause to rest in the [mothers’] wombs for a term set [by Us], and then We bring you forth as infants and [allow you to live] so that [some of] you might attain to maturity: for among you are such as are caused to die [in childhood], just as many a one of you is reduced in old age to a most abject state, ceasing to know anything of what he once knew so well. And [if, O man, thou art still in doubt as to resur­rection, consider this:] thou canst see the earth dry and lifeless - and [suddenly,] when We send down waters upon it, it stirs and swells and puts forth every kind of lovely plant!”

Man is doubtful about the life hereafter for the simple reason that he is unable to understand how a human being who is dead and gone can come back to life. He wonders how a dead universe can become a live universe. The reply to this question can be found in the structure of our present world itself. What is the present world? It is nothing but a change from one condition to another. What we call a ‘live’ existence is in fact the result of a change, a metamorphosis of a non-living existence. An analysis of the human body shows that it is composed of iron, carbon, calcium, salts, water, gases, etc. These compounds which comprise the human body are all lifeless. But these inanimate soul-less things convert into animate objects having souls and start moving about in the shape of human beings. In the case of human beings, therefore, when non-living things have initially taken the shape of living things, the assertion that, once again, non-living things will change into living things, is not at all surprising. Similarly, if one looks at the green vegetation growing on the earth, it will be seen that it is formed from a number of constituents found in the soil. All these constituents are initially devoid of the qualities found in vegetation. Yet this type of transformation takes place every day before our eyes. Then why should we have doubts about the recurrence of such a feasible event? The fact is that the coming into existence of the first world in itself proves the feasibility of the coming into existence of the second world. After experiencing one world, the understanding of a second world, rationally and logically, is not at all difficult.
