O people , if you doubt your revival on the Day of Resurrection , then ponder that We created you from dust , then from a drop of liquid , then from a clot , then from a piece of flesh formed and without form , so that We show you Our signs for you ; and We keep whomever We want inside the mothers ’ wombs up to an appointed time , then extract you as infants , then in order that you reach your puberty ; and among you is one who dies earlier , and among you is one put to the most abject age , so after having knowledge , knows nothing ; and you see the earth desolate , then when We sent down water upon it , it freshened up and developed and produced beautiful pairs of all kinds .
