He it is who sendeth down water from the sky, and therewith we bring forth buds of every kind ; we bring forth the green blade from which we bring forth the thick - clustered grain; and from the date-palm, from the pollen thereof, spring pendant bunches ; and ( we bring forth ) gardens of grapes, and the olive and the pomegranate , alike and unlike. Look upon the fruit thereof, when they bear fruit, and upon  its ripening. Lo! herein verily are portents for a people who believe.
