In those verses Allah mentions the condition of those atheists negating the concept of the day of resurrection and giving them answer in this way: “And says man: What! When I am dead shall I truly be brought forth alive? Does not man remember that We created him before, when he was nothing? So, (O Prophet (s.a.w.a.)) by your Lord!
We will most certainly gather them together and the Shaitans, As you have observed, the verse that the author has used to base his argument is in reply to those who say that how it is possible that man after his death, when the particles of his body have separated from each other and scattered, can again become alive and come to his first (original) condition? Have they forgotten the beginning of their creation? Do they not know that We brought them into existence from nothing?
Those who know, that We have that 'Power', why they think that to resurrect the dead again is impossible for Us. Whereas their initial creation was as per the laws of permanence of matter and strength, which can never be destroyed, and remains existing forever. The God Who has the power to bring man into existence from nothing, can He not put together the scattered parts of his body?
Therefore the verses cannot in any way be construed to mean that man before attaining this stage of excellence was in the category of unlimited living existences. But this verse is like many other verses, which were revealed regarding the proof of Qiyamat for atheists. Tafseer of the second Ayat: When a newborn child in a very strong winter is separated from its parents as a result of some misfortune, naturally that child will die very soon.
Now if some good person reaches there on time and takes that child to his home and looks after him/her as an affectionate father and that child is lucky with his love and receives his full favor filled with trays of grace, then that child of yesterday who was without any preparations today will find himself to be in such a situation that he apparently will be the basis of all necessaries of life and be independent of others.
Many a times it is possible that arrogance and selfishness in that boy may obliterate the remembrance of that virtuous man's previous love from his heart, and he for the sake of his temporary benefits may fight and quarrel with that man and become guilty of being ungrateful.
