The Messenger of Allah ﷺ said, "In Paradise there is a tree whose shade a rider could traverse for a hundred years."
عن رسول الله ﷺ أنه قال: إن في الجنة لشجرة يسير الراكب في ظلها مائة سنة.
Muslim narrated it in the Book of Paradise, Its Description of Bliss and Its People (2826), from Qutayba bin Saeed, who said, Layth narrated to us, from Saeed bin Abu Saeed Maqburi, from his father, from Abu Hurairah, and he mentioned it. In another narration, from a different route, he added, "he does not finish traversing it."
