Divorce - 65:11
He has sent a messenger. He recites to you the clear signs of Allah to bring those who believe and do righteous deeds out of darkness into light. Whoever believes in Allah and does righteous deeds, He will admit him into Gardens in which rivers flow, where they will abide forever. Allah has given him a goodly sustenance.
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?
