Qura’n has named some people and some nations who will remain forever in Hell as follows:
The disbelievers
They can be those who do not believe in the Origin of creation and the resurrection, the polytheists, those who deny the signs of God, those who are the enemies of God and His Messenger, and renegades about whom verse 116 of Surah Al Imran says: “ Surely those who rejected faith will not find help in their offspring and properties against God. Therein they will abide.” (1)
(1) There are numerous verses in the Qura’n on this issue like verse 26 of Surah A’raf that speaks about those who deny the signs of God; verse 6 of Surah Anbiya which criticizes the polytheists and the people of the Books, verse 17 of Surah Taubah that speaks about the eternal punishment of the polytheists; verse 21`7 of Surah Baqarah and verse 88 of al Imran speak specifically about those who renege and verse 28 of Surah Fussilat declares that the enemies of God shall stay in hell forever.
