The Prophet (saw) told us clearly about the rivers of Paradise.
He said that during his Israa' (Night Journey): "...I saw four rivers flowing out from beneath Sidrat al-Muntahaa, two visible and two hidden. He asked, "O Jibreel, What are these rivers?" He said, "The two hidden rivers are rivers of Paradise, and the two visible rivers are the Nile and the Euphrates". [Muslim, Kitaab al-Imaan, Baab al-Israa', 1/150, no. 164; al-Bukhaari reports the same from Anas ibn Maalik, Jaami' al-Usool, 10/507, narrated bt Abu Awanah, al-Isma'eelee and at-Tabaranee in as-Sagheer]
