The Messenger of Allah ﷺ said, "Four rivers flow from Paradise, the Furat, the Nile, the Sayhan, and the Jayhan."
قال رسول الله ﷺ: فجرت أربعة أنهار من الجنة: الفرات، والنيل، وسيحان، وجيحان.
Ahmad (7544) and Abu Yaala (5921) both narrated it through routes from Muhammad bin Amr, from Abu Salama, from Abu Hurairah, who said, and then he mentioned it. Its chain is hasan because of Muhammad bin Amr, who is Ibn Alqama Laythi, for he is hasan al-hadith.
