An-Nahl - ১৬:৪

خَلَقَ الإِنسَانَ مِن نُّطْفَةٍ فَإِذَا هُوَ خَصِيمٌ مُّبِينٌ
[16:4]
He created man from a small seed and lo! he is an open contender.
He has created man from a sperm-drop; and behold this same (man) becomes an open disputer!
He hath created man from a drop of fluid, yet behold! he is an open opponent.
