Al-Hijr - 15:48

لاَ يَمَسُّهُمْ فِيهَا نَصَبٌ وَمَا هُم مِّنْهَا بِمُخْرَجِينَ
[15:48]
Toil shall not afflict them in it, nor shall they be ever ejected from it.
There no sense of fatigue shall touch them, nor shall they (ever) be asked to leave.
Toil cometh not unto them there, nor will they be expelled from thence.
