And it is He Who has sent down water from the heavens, and thereby We have brought vegetation of every kind, and out of this We have brought forth green foliage and then from it close-packed ears of corn, and out of the palm-tree from the sheath of it - thick clustered dates, hanging down with heaviness, and gardens of vines, and the olive tree, and the pomegranate - all resembling one another and yet so different. Behold their fruit when they bear fruit and ripen! Surely, in all this there are signs for those who believe.
