Abu Hurairah (RA) reported Allah's Messenger (ﷺ) as saying: Saihan, Jaihan, Euphrates and Nile are all among the rivers of Paradise.
Explanation & Benefits
Shaykh Maulana Abdul Aziz Alvi
Hadith Commentary: Benefits and Issues: Sayhan and Jayhan are two rivers located on the Syrian border, which are different from Sahiun and Jahiun (the two rivers of Uzbekistan). The Euphrates (Furat) is located in Iraq and the Nile (Nil) in Egypt. Their source and origin are in Paradise. This is the view of Qadi Iyad, Nawawi, Hafiz Ibn Hajar, Mulla Ali Qari, and others (). However, the reality and nature of this are beyond the grasp of our intellect.
