Quran Fatir 35:35
ٱلَّذِيٓ أَحَلَّنَا دَارَ ٱلۡمُقَامَةِ مِن فَضۡلِهِۦ لَا يَمَسُّنَا فِيهَا نَصَبٞ وَلَا يَمَسُّنَا فِيهَا لُغُوبٞ
Translation
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]."
