The Messenger of Allah ﷺ said in a long hadith, "When Allah admits the people of Paradise into Paradise and the people of the Fire into the Fire, death will be brought forth in the form of a ram and made to stand upon the wall between the people of Paradise and the people of the Fire."Then it will be announced, "People of Paradise!" and they will look out fearfully.Then it will be announced, "People of the Fire!" and they will look out joyfully, hoping for intercession.It will be said to the people of Paradise and the people of the Fire, "Do you recognize this?"Both groups will reply, "We recognize it. This is death, which was assigned to us."Then it will be laid down and slaughtered upon the wall between Paradise and the Fire. Then it will be announced, "People of Paradise, eternity with no death! People of the Fire, eternity with no death!"
أن رسول الله ﷺ قال في حديث طويل: فإذا أدخل الله أهل الجنة الجنة وأهل النار النار، قال: أتي بالموت مكببا فيوقف على السور الذي بين أهل الجنة وأهل النار، ثم يقال: يا أهل الجنة فيطلعون خائفين، ثم يقال: يا أهل النار فيطلعون مستبشرين يرجون الشفاعة، فيقال لأهل الجنة وأهل النار: هل تعرفون هذا؟ فيقولون هؤلاء وهؤلاء: قد عرفناه، هو الموت الذي وكل بنا، فيضجع فيذبح ذبحا على السور الذي بين الجنة والنار، ثم يقال: يا أهل الجنة خلود لا موت، ويا أهل النار خلود لا موت.
Tirmidhi (2557) and Ibn Khuzayma in Tawhid (150) both narrated it through the route of Abdul-Aziz bin Muhammad Darawardi, from Ala bin Abdul-Rahman, from his father, from Abu Hurairah, who related it.Its chain is hasan because of Abdul-Aziz bin Muhammad Darawardi, for there is disagreement about him, though his hadith is hasan when it does not contradict the reliable narrators.Tirmidhi said, "Hasan sahih."
