The example [i.e., description] of Paradise, which the righteous have been promised, is [that] beneath it rivers flow. Its fruit is lasting, and its shade. That is the consequence for the righteous, and the consequence for the disbelievers is the Fire.
The description of Paradise that those mindful of Allah, by fulfilling His instructions and avoiding His prohibitions, have been promised is that rivers flow below its palaces, its fruits are perpetual and do not ever end unlike the fruit of the world, and its shade is everlasting without ever retracting. That is the outcome that awaits those who are mindful of Allah, by fulfilling His instructions and avoiding His prohibitions. The outcome of the disbelievers is the Fire, which they will enter to remain there forever.
