Severity of Hellfire

وَٱلَّذِينَ يَقُولُونَ رَبَّنَا ٱصْرِفْ عَنَّا عَذَابَ جَهَنَّمَ ۖ إِنَّ عَذَابَهَا كَانَ غَرَامًا

And those who say, "Our Lord, avert from us the punishment of Hell. Indeed, its punishment is ever adhering;

ثُمَّ صُبُّوا۟ فَوْقَ رَأْسِهِۦ مِنْ عَذَابِ ٱلْحَمِيمِ

Then pour over his head from the torment of scalding water."
