The Iron - 57:12
"On the Day when you see the light of the believing men and women radiating from before them and on their right sides, they will say: "Good news, today you have Gardens beneath them rivers flowing, where you will abide forever. This is the greatest victory."
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?
