I heard the Messenger of Allah ﷺ say, "Indeed, there are people who will be brought out of the Fire after having been scorched within it. They will then be taken to a river in Paradise called the River of Life, where they will bathe. They will emerge from it like sprouting plants."
حدثنا زيد بن الحباب حدثنا الحسين بن واقد الليثي حدثني أبو الزبير حدثني
سمعت رسول الله ﷺ يقول إن أقواما يخرجون من النار بعدما امتحشوا فيها فينطلق بهم إلى نهر في الجنة يقال له نهر الحياة فيغتسلون فيه فيخرجون منه أمثال الثعارير

Its isnad is sahih. Husayn bin Waqid Marwazi, the judge, is trustworthy, and I have not found anyone who said "Laythi" except Ahmad, and this should be accepted from him. The hadith has already appeared at 14428.
