He it is who sends down rain from the heavens; and We bring forth therewith growths of all kinds; and We bring forth there from green crops, from which We bring forth grain in full ear; and the palm, from its sheathes come clusters of dates within reach; and gardens of grapes and olives and pomegranates, alike and unlike; - behold its fruit when it fruits and ripens! Verily, in that you have a sign for the people who believe.
