Abu Hurairah reported that the Prophet ﷺ said, "A caller will proclaim, 'It is yours to be healthy and never fall ill. It is yours to live and never die. It is yours to remain young and never grow old. It is yours to enjoy bliss and never feel sorrow.' That is the meaning of His saying , 'And they will be called, This is the Garden which you have been made to inherit for what you used to do' [Araf 7:43]."
وأبي هريرة، عن النبي ﷺ قال: ينادي مناد: إن لكم أن تصحوا، فلا تسقموا أبدا. وإن لكم أن تحيوا، فلا تموتوا أبدا. وإن لكم أن تشبوا، فلا تهرموا أبدا. وإن لكم أن تنعموا، فلا تبتئسوا أبدا. فذلك قوله عز وجل: {ونودوا أن تلكم الجنة أورثتموها بما كنتم تعملون}
Muslim narrated it in the Book of Paradise (2837) via Abdul-Razzaq, who said, Thawri said, "Abu Ishaq related to me that Aghar told him, from Abu Saeed Khudri and Abu Hurairah," who said, and then he mentioned it.
