Al-Ghaafir 40:67

It is He Who created you from dust[15], then from a sperm drop[16], then from a clinging clot[17]. Then He brings you out as an infant, so that you may reach your age of full strength, then you become old, even though some of you may die earlier – and so that you may reach an appointed term[18], and so that you may understand.

[15] i.e., your father Adam.
[16] i.e., the union of male and female gametes, sperm and egg; the zygote.
[17] Which resembles a leech.
[18] That is decreed for your death.

It is He who created you from dust, then from a sperm-drop, then from a clinging clot; then He brings you out as a child; then [He develops you] that you reach your [time of] maturity, then [further] that you become elders. And among you is he who is taken in death before [that], so that you reach a specified term;[1378] and perhaps you will use reason.

[1378] The time decreed for your death.

67. It is He, Who has created you (Adam) from dust, then from a Nutfah [mixed semen drops of male and female sexual discharge (i.e. Adam’s offspring)] then from a clot (a piece of coagulated blood), then brings you forth as an infant, then (makes you grow) to reach the age of full strength, and afterwards to be old (men and women)- though some among you die before,- and that you reach an appointed term in order that you may understand.[5]

[5] (V.40:67) See the footnote of (V.22:5).

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.
