O men! if ye doubt as to the resurrection, yet, of a truth, have We created you of dust, then of the moist germs of life, then of clots of blood, then of pieces of flesh shapen and unshapen, that We might give you proofs of our power! And We cause one sex or the other, at our pleasure, to abide in the womb until the appointed time; then We bring you forth infants; then permit you to reach your age of strength; and one of you dieth, and another of you liveth on to an age so abject that all his former knowledge is clean forgotten! And thou hast seen the earth dried up and barren: but when We send down the rain upon it, it stirreth and swelleth, and groweth every kind of luxuriant herb.
