And He it is Who sends down water from the cloud, then We bring forth with it buds of all (plants), then We bring forth from it green (foliage) from which We produce grain piled up (in the ear); and of the palm-tree, of the sheaths of it, come forth clusters (of dates) within reach, and gardens of grapes and olives and pomegranates, alike and unlike; behold the fruit of it when it yields the fruit and the ripening of it; most surely there are signs in this for a people who believe.

Do they not then consider what is before them and what is behind them of the heaven and the earth? If We please We will make them disappear in the land or bring down upon them a portion from the heaven; most surely there is a sign in this for every servant turning (to Allah).
