Read and reflect on verse 4200 from Surah Ghafir: It is He who creates you out of dust, and then out of a drop of sperm, and then out of a germ-cell; and then He brings you forth as children; and then...
هُوَ الَّذِي خَلَقَكُمْ مِنْ تُرَابٍ ثُمَّ مِنْ نُطْفَةٍ ثُمَّ مِنْ عَلَقَةٍ ثُمَّ يُخْرِجُكُمْ طِفْلًا ثُمَّ لِتَبْلُغُوا أَشُدَّكُمْ ثُمَّ لِتَكُونُوا شُيُوخًا ۚ وَمِنْكُمْ مَنْ يُتَوَفَّىٰ مِنْ قَبْلُ ۖ وَلِتَبْلُغُوا أَجَلًا مُسَمًّى وَلَعَلَّكُمْ تَعْقِلُونَ
It is He who creates you out of dust, and then out of a drop of sperm, and then out of a germ-cell; and then He brings you forth as children; and then [He ordains] that you reach maturity, and then, that you grow old - though some of you [He causes to] die earlier -: and [all this He ordains] so that you might reach a term set [by Him], and that you might [learn to] use your reason.
