The example of the life of this world is similar to the water which We sent down from the sky, so due to it the earth’s vegetation grew in abundance - that which men and cattle eat; to the extent that when the earth has taken on her ornaments and is well beautified, and her owners thought that it is within their control, Our command came to it at night or at day - so We made it harvested as if it had not existed yesterday; this is how We explain the verses for the people who ponder.
