The Cave - 18:31
For them are the gardens of Adn (gardens) from which rivers flow. Therein they will be adorned with bracelets of gold, and they will wear green garments woven of silk and velvet. There they will recline on couches. What a good reward and what a good abode
The rivers in Paradise:
Muhammad/47:15
This is the example of Paradise promised to the righteous: In it are rivers of pure water, rivers of milk whose taste does not spoil, rivers of intoxicants that give flavor to those who drink them, and rivers of strained honey. For them therein are all kinds of produce and forgiveness from their Lord. Will their condition be like that of those who are made to drink of boiling water which stays in the fire permanently and tears their bowels?
