This chapter clearly shows that Allah, the Exalted returns the same body that had obeyed or disobeyed Him in life, in order to reward or punish it just like He rewards the soul itself, which believes in Him and punishes the one, which disbelieves in Him.
That does not mean that Allah, the Exalted creates another soul, which will be rewarded or punished, as some people say.
Such people do not understand the nature of the Resurrection, which the Messengers informed mankind about.
They claim that Allah, the Exalted will create another body that is different in all aspects and that Allah will reward or punish it.
They also say that the soul is simply a part of the body, so Allah will create another soul other than this one and a body other than this body.
This belief is contrary to what the Messengers taught, and what the Qur’an, Sunnah, and other Books of Allah, the Exalted say. This is in fact denial of the Resurrection and adopting the belief of the disbelievers.
Such people find it difficult to comprehend that Allah, the Exalted will recreate the very same body and soul that had known life.
They cannot imagine how the body will become bones and dust and Allah will create it again in its original form.
Allah quotes them as saying,
أَإِذَا مِتْنَا وَكُنَّا تُرَابًا وَعِظَامًا أَإِنَّا لَمَبْعُوثُونَ
which means, “When we are dead and have become dust and bones, shall we (then) verily be resurrected? (As-Saffat, 37:16)
And such people also say,
ذَٰلِكَ رَجْعٌ بَعِيدٌ
which means, ” That is a far return.” (Qaf, 50:3)
If what they assert is true and another body other than the one that had known in life is rewarded or punished, this will neither be Resurrection nor returning back, indeed, it would be a new creation altogether.
And the following verse would be rendered meaningless. May Allah forbid!
قَدْ عَلِمْنَا مَا تَنقُصُ الْأَرْضُ مِنْهُمْ ۖ وَعِندَنَا كِتَابٌ حَفِيظٌ
which means, “We know that which the earth takes of them (their dead bodies). 11 (Qaf, 50:4)
Allah answered the question that He, the Exalted will separate these pieces which had mixed with the earth and turned it into elements which are difficult to be separated.
So Allah, the Exalted told mankind that He knows what the earth is taking from their flesh, bones, and hair and just as He knows these pieces He is capable of separating, and gathering them after being separated, and creating them again.
He, the Exalted decides the time of Resurrection by His perfect knowledge, power, and wisdom.
