Is Hell Eternal?
We read the Quran in its totality. Some other verses indicate that God might not let the hell go eternal. الَّذِينَ شَقُوا فَفِي النَّارِ لَهُمْ فِيهَا زَفِيرٌ وَشَهِيقٌ ﴿١٠٦﴾ خَالِدِينَ فِيهَا مَا دَامَتِ السَّمَاوَاتُ وَالْأَرْضُ إِلَّا مَا شَاءَ رَبُّكَ ۚ إِنَّ رَبَّكَ فَعَّالٌ لِّمَا يُرِيدُ ﴿ If someone doesn’t ct upon his threat, it is not considered violation of his promise but an act of generosity and pardon. However the rejectors of truth won’t be able to enter the paradise as it is against the sense of justice .
Quran has clearly made descriptive statements of what God will say to disbelievers and other ayahs in which it is said that they will abide in there forever.
Yes you are right. In almost all, and there are numerous, of ayahs, except one or two.
