هُوَ ٱلَّذِى خَلَقَكُم مِّن تُرَابٍۢ ثُمَّ مِن نُّطْفَةٍۢ ثُمَّ مِنْ عَلَقَةٍۢ ثُمَّ يُخْرِجُكُمْ طِفْلًۭا ثُمَّ لِتَبْلُغُوٓا۟ أَشُدَّكُمْ ثُمَّ لِتَكُونُوا۟ شُيُوخًۭا ۚ وَمِنكُم مَّن يُتَوَفَّىٰ مِن قَبْلُ ۖ وَلِتَبْلُغُوٓا۟ أَجَلًۭا مُّسَمًّۭى وَلَعَلَّكُمْ تَعْقِلُونَ
He it is Who created you from dust, then from a drop (of seed) then from a clot, then bringeth you forth as a child, then (ordaineth) that ye attain full strength and afterward that ye become old men - though some among you die before - and that ye reach an appointed term, that haply ye may understand.
