That this punishment would be everlasting for disbelievers has been made clear through the third verse (37).
- 5:3737
يُرِيدُونَ أَنْ يَخْرُجُوا مِنَ النَّارِ وَمَا هُمْ بِخَارِجِينَ مِنْهَا ۖ وَلَهُمْ عَذَابٌ مُقِيمٌ
They will desire to come forth from the Fire, but they shall not be able to come forth therefrom, and theirs shall be a torment lasting.
