Paradise and its eternal nature

خَـٰلِدِينَ فِيهَا ۚ حَسُنَتْ مُسْتَقَرًّا وَمُقَامًا

Abiding eternally therein. Good is the settlement and residence.

ٱلَّذِىٓ أَحَلَّنَا دَارَ ٱلْمُقَامَةِ مِن فَضْلِهِۦ لَا يَمَسُّنَا فِيهَا نَصَبٌ وَلَا يَمَسُّنَا فِيهَا لُغُوبٌ

He who has settled us in the home of duration [i.e., Paradise] out of His bounty. There touches us not in it any fatigue, and there touches us not in it weariness [of mind]."

لَا يَذُوقُونَ فِيهَا ٱلْمَوْتَ إِلَّا ٱلْمَوْتَةَ ٱلْأُولَىٰ ۖ وَوَقَىٰهُمْ عَذَابَ ٱلْجَحِيمِ

They will not taste death therein except the first death, and He will have protected them from the punishment of Hellfire
