Abu Sa'id and Abu Hurairah (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) said, "When the dwellers of Jannah enter Jannah, an announcer will call: (You have a promise from Allah that) you will live therein and you will never die; you will stay healthy therein and you will never fall ill; you will stay young and you will never become old; you will be under a constant bliss and you will never feel miserable." .
