quran:71:14 –

While He has created you in stages?  

when verily He created you in stages? (atwār is the plural of tūr, which means a state). Thus the sperm-drop is one state, the blood clot is another state, and so on, until the creation of the human being is complete: reflecting on ˹the manner of˺ his creation necessarily leads to belief in his Creator.
القرآن:٧١:١٤ –

وَقَدْ خَلَقَكُمْ أَطْوَارًا  

{وقد خلقكم أطوارا} جمع طور وهو الحال، فطورا نطفة وطورا علقة إلى تمام خلق الإنسان، والنظر في خلقه يوجب الإيمان بخالقه.
