Abu Sa'id al-Khudri and Abu Huraira both reported Allah's Messenger (ﷺ) as saying
There would be an announcer (in Paradise) who would make this announcement: Verily I there is in store for you (everlasting) health and that you should never fall ill and that you live (for ever) and do not die at all. And that you would remain young and never grow old. And that you would always live in affluent circumstances and never become destitute, as words of Allah, the Exalted and Glorious, are:" And it would be announced to them: This is the Paradise. You have been made to inherit it for what you used to do". (VII; 43)
