quran:44:48 –

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

Then pour over his head the torture of boiling water!’, that is to say, the boiling water which is evertorturous (this ˹use of ‘the torture of boiling water’˺ is rhetorically more intense than what is stated by the verse: boiling water will be poured over their heads ˹Q. 22:19˺).
القرآن:٤٤:٤٨ –

ثُمَّ صُبُّوا فَوْقَ رَأْسِهِ مِنْ عَذَابِ الْحَمِيمِ  

(ثم صبوا فوق رأسه من عذاب الحميم) أي من الحميم الذي لا يفارقه العذاب فهو أبلغ مما في آية "" يصب من فوق رؤوسهم الحميم "".
