Hakim b. Mu'awiya reported God's messenger as saying, "In paradise there are a great river of water, a great river of honey, a great river of milk and a great river of wine; then the smaller rivers will be divided off."
Tirmidhi transmitted it, and Darimi transmitted it from Mu'awiya. (Mirqat, 5, 301 says this is most probably Mu'awiya b. Abu Sufyan because Hakim's father is not known to have been a Companion of the Prophet.)
