ثُمَّ صُبُّواْ فَوۡقَ رَأۡسِهِۦ مِنۡ عَذَابِ ٱلۡحَمِيمِ
"Then pour over his head the Penalty of Boiling Water,<br/>
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]).
