The Prophet ﷺ said, "It will be said to the people of Paradise, 'Eternity without death,' and to the people of the Fire, 'People of the Fire, eternity without death.'"
قال النبي ﷺ: يقال لأهل الجنة: خلود لا موت، ولأهل النار يا أهل النار خلود لا موت.
Bukhari narrated it in the chapter on Raqaq (6545) from Abu Yaman, who said, Shuayb told us, Abu Zinad told us, from Araj, from Abu Hurairah, who said, "[he then mentioned it]." Imam Ahmad narrated it (8535) through another route from Abu Zinad with the same chain, as a raised hadith, and its wording was, "When the people of Paradise enter Paradise and the people of Hell enter Hell, a caller will cry out, 'O people of Paradise, everlasting life, no death in it. O people of Hell, everlasting life, no death in it.'"Layth bin Saad said, "Khalid bin Yazid mentioned to me that he heard Abu Zubayr relate something similar from Jabir and Ubayd bin Umayr, except that he related from them both that this comes after the intercessions and after those who will be brought out of Hell."
