Surah Hud — Ayah 107 (11:107)
خَٰلِدِينَ فِيهَا مَا دَامَتِ ٱلسَّمَٰوَٰتُ وَٱلۡأَرۡضُ إِلَّا مَا شَآءَ رَبُّكَۚ إِنَّ رَبَّكَ فَعَّالٞ لِّمَا يُرِيدُ ١٠٧
English translation (Saheeh International)
[They will be] abiding therein as long as the heavens and the earth endure, except what your Lord should will. Indeed, your Lord is an effecter of what He intends.
Brief commentary
They will live in it eternally and will not come out of it for as long as the heavens and the earth last, except for those sinful monotheists whom Allah wills to remove from it. Your Lord, O Messenger, is the One Who does whatever He wishes and nothing can force Him to do something.
