The life of this world is just like rain We send down from the sky, producing a mixture of plants which humans and animals consume. Then just as the earth looks its best, perfectly beautified, and its people think they have full control over it, there comes to it Our command by night or by day, so We mow it down as if it never flourished yesterday! This is how We make the signs clear for people who reflect.

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 in 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 Ayât (proofs, evidence, verses, lessons, signs, revelations, laws, etc.) in detail for the people who reflect.
