The Cow - 2:25
"Give glad tidings to those who believe and do righteous deeds with gardens in which rivers flow. When they are offered sustenance from the produce therein, they say: "This is what was offered to us before". So they are given metaphorical descriptions (analogies). For them therein are pure wives, and they will abide therein forever."
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?
