Sahih Muslim 2837
The Book of Paradise, its Description, its Bounties and its Inhabitants
The Eternal Delight Of The People Of Paradise, And The Verse In Which Allah Says: "And It Will Be Announced To Them: This Is The Paradise Which You Have Inherited For What You Used To Do"
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)
