And He it is Who sends down water from the clouds, then We bring forth with it buds of all (plants), then We bring forth from it green (foliage), from which We produce clustered grain; and of the date-palm, of the sheaths of it, come forth clusters (of dates) within reach; and gardens of grapes and the olive and the pomegranate, alike and unlike. Look at the fruit of it when it bears fruit and the ripening of it. Surely there are signs in this for a people who believe!
