Allah would admit the inmates of Paradise into Paradise and the inmates of Hell into Hell. Then the announcer would stand between them and say: 0 inmates of Paradise, there is no death for you,0 inmates of Hell, there is no death for you. You would live for ever therein. (Using translation from Muslim 2850a)
إِنَّ رَسُولَ اللهِ ﷺ قَالَ يَدْخُلُ أَهْلُ الْجَنَّةِ الْجَنَّةَ قَالَ عَبْدُ اللهِ بْنُ أَحْمَدَ قَالَ أَبِي وحَدَّثَنَاهُ سَعْدٌ قَالَ يُدْخِلُ اللهُ أَهْلَ الْجَنَّةِ الْجَنَّةَ وَأَهْلَ النَّارِ النَّارَ ثُمَّ يَقُومُ مُؤَذِّنٌ بَيْنَهُمْ فَيَقُولُ يَا أَهْلَ الْجَنَّةِ لَا مَوْتَ وَيَا أَهْلَ النَّارِ لَا مَوْتَ كُلٌّ خَالِدٌ فِيمَا هُوَ فِيهِ
