And indeed, you have already known the first form of creation, why then do you not remember?
meaning, `you know that Allah has created you after you were nothing. He created you and gave you hearing, sight and hearts. Will you not then remember and take heed that He Who is able to create you in the beginning is more able to bring you back and resurrect you to life anew?' Allah the Exalted said in other Ayat,
وَهُوَ الَّذِى يَبْدَأُ الْخَلْقَ ثُمَّ يُعِيدُهُ وَهُوَ أَهْوَنُ عَلَيْهِ
And He it is Who originates the creation, then He will repeat it; and this is easier for Him. (30;27),
أَوَلَا يَذْكُرُ إلاِنْسَـنُ أَنَّا خَلَقْنَاهُ مِن قَبْلُ وَلَمْ يَكُ شَيْياً
Does not man remember that We created him before, while he was nothing? (19;67),
أَوَلَمْ يَرَ الاِنسَـنُ أَنَّا خَلَقْنَـهُ مِن نُّطْفَةٍ فَإِذَا هُوَ خَصِيمٌ مٌّبِينٌ
وَضَرَبَ لَنَا مَثَلً وَنَسِىَ خَلْقَهُ قَالَ مَن يُحىِ الْعِظَـمَ وَهِىَ رَمِيمٌ
قُلْ يُحْيِيهَا الَّذِى أَنشَأَهَأ أَوَّلَ مَرَّةٍ وَهُوَ بِكُلِّ خَلْقٍ عَلِيمٌ
Does not man see that We have created him from Nutfah. Yet behold he (stands forth) as an open opponent. And he puts forth for Us a parable, and forgets his own creation.
He says;"Who will give life to these bones after they are rotten and have become dust"
Say;"He will give life to them Who created them for the first time! And He is the All-Knower of every creation." (36;77-79),
and,
أَيَحْسَبُ الاِنسَـنُ أَن يُتْرَكَ سُدًى
أَلَمْ يَكُ نُطْفَةً مِّن مَّنِىٍّ يُمْنَى
ثُمَّ كَانَ عَلَقَةً فَخَلَقَ فَسَوَّى
فَجَعَلَ مِنْهُ الزَّوْجَيْنِ الذَّكَرَ وَالاٍّنثَى
أَلَيْسَ ذَلِكَ بِقَـدِرٍ عَلَى أَن يُحْيِىَ الْمَوْتَى
Does man think that he will be left neglected? Was he not a Nutfah of semen emitted? Then he became an `Alaqah (a clot); then shaped and fashioned in due proportion. And made of him two sexes, male and female. Is not He able to give life to the dead? (75;36-40
