Why are the descriptions of Paradise in the Quran and Hadith limited to things found in this world, even though it has been stated that it contains what no eye has seen, no ear has heard, and no human heart has conceived, and is there wisdom in this?

Paradise transcends what the mind can conceive, containing what no eye has seen, no ear has heard, and no human heart has ever imagined. Allah will grant its inhabitants beyond their desires, for therein they will have whatever they wish, whatever their souls crave, and whatever they ask for. Paradise is as vast as the heavens and the earth, with rivers flowing beneath it—of water, milk, wine, and honey—and its fruits are everlasting. Its dwellings are built with bricks of gold and bricks of silver, their mortar is musk, and their pebbles are pearls and rubies. It contains chambers whose exteriors can be seen from their interiors, and hollowed out tents of pearls, and trees with trunks of gold. The inhabitants of Paradise increase in beauty and handsomeness every Friday. They will never fall ill, die, age, or despair. They will enter Paradise in the image of the moon on its fullest night; they will not urinate or defecate, their combs will be of gold, their perspiration musk, and they will not sleep, for sleep is the sibling of death.
