Verily the likeness of ( this ) worldly life is as the water ( rain ) which We send down from the sky , so by it arises the intermingled produce of the earth of which men and cattle eat until when the earth is clad with its adornments and is beautified , and its people think that they have all the powers of disposal over it , Our Command reaches it by night or by day and We make it like a clean-mown harvest , as if it had not flourished yesterday ! Thus do We explain the Ayat ( proofs , evidences , verses , lessons , signs , revelations , laws , etc . ) in detail for the people who reflect .
