Allah created humanity and knows what gives the most pleasure to one's soul. The pleasure a person derives from green lands is a manifestation of this fact.
But those who have fear of their Lord will have high-ceilinged halls, and more such halls built one above the other, and rivers flowing under them. That is Allah's promise. Allah does not break His promise.
Places with "rivers flowing under them" are mentioned in verses that describe Paradise. Residences and mansions in Paradise are said to be constructed on such places. Allah's promise to reward His true servants with places that have rivers flowing under them is a clear sign of the favorable nature of such places also in this world.
Gardens of fruits are also mentioned in the Qur'an as beautiful places. Allah makes fruits with different and striking smells, tastes, and colors grow out of dry soil. Tree branches laden with these fruits and gardens of such trees are obviously among the most beautiful places on earth. Again, from the Qur'an we learn how wonderful and admirable the gardens of Paradise will be in the eternal life.
A verse refers to gardens and fruits as follows:
He sends down water from the sky, from which We bring forth growth of every kind, and from that We bring forth the green shoots. And from them We bring forth close-packed seeds, and from the spathes of the date-palm date clusters hanging down, and gardens of grapes and olives and pomegranates, both similar and dissimilar. Look at their fruits as they bear fruit and ripen. There are Signs in that for people who have faith.
Date palms from which "date clusters hang down" are striking both in appearance and taste. Besides, gardens of grapes, olives, and pomegranates, which vary in taste and color, have an impressive view once they start to bear their fruits and reach their full maturity.
