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.
