Then by means of this (rain) We bring forth vegetation of every kind out of which We produce green (foliage) from which We bring forth clustered grain packed one over the other, clusters of date-palm hanging low from its spathe and gardens of grapes, olives and (also) pomegranates (which from many aspects look) alike but (in products, tastes and effects) are unlike. Look at the fruit of the tree when it bears fruit, and (also observe) when it ripens. Verily in these are Signs for those who believe.
