And those who have no knowledge say: Why does not Allah speak to us or a sign come to us? Even thus said those before them, the like of what they say; their hearts are all alike. Indeed We have made the communications clear for a people who are sure.

The likeness of this world's life is only as water which We send down from the cloud, then the herbage of the earth of which men and cattle eat grows luxuriantly thereby, until when the earth puts on its golden raiment and it becomes garnished, and its people think that they have power over it, Our command comes to it, by night or by day, so We render it as reaped seed; produce, as though it had not been in existence yesterday; thus do We make clear the communications for a people who reflect.
