The example of [this] worldly life is but like rain which We have sent down from the sky that the plants of the earth absorb - [those] from which men and livestock eat - until, when the earth has taken on its adornment and is beautified and its people suppose that they have capability over it, there comes to it Our command by night or by day, and We make it as a harvest, as if it had not flourished yesterday. Thus do We explain in detail the signs for a people who give thought.
