O mankind! If you have any doubt concerning Resurrection, then know that it is surely We Who created you from dust, then from a drop of sperm, then from a clot of blood, then from a little lump of flesh, some of it shapely and other shapeless. (We are rehearsing this) that We may make the reality clear to you. We cause (the drop of sperm) that We please to remain in the wombs till an appointed time. We bring you forth as infants (and nurture you) that you may come of age. Among you is he that dies (at a young age) and he who is kept back to the most abject age so that after once having known, he reaches a stage when he knows nothing. You see the earth dry and barren and then no sooner than We send down water upon it, it begins to quiver and swell and brings forth every kind of beauteous vegetation.
