Water will be asked for galloping it down, so that boiled water will be given to them; when it is brought closer to them it will melt his face and complete skin of his face will fall into it.

Translation from Kanz-ul-Iman: And who will be given boiling water to drink so that it tears their guts apart? (Part 26, Surah Muhammad, verse 15)

It has been narrated that the person, upon whom the lightest torment of Hell will be inflected, will feel the pain of this torment so much that he will think that the most painful torment is being inflicted to him alone, though it is contrary to the fact. It is narrated by Sayyiduna Ibn ‘Abbas رَضِىَ الـلّٰـهُ تَـعَالٰی عَـنْهُمَا that the Holy Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has said, ‘One from among the dwellers of Hell to whom the slightest punishment will be given will be made to wear the shoes of fire, causing his brain to boil.’ (Sahih Bukhari, vol. 4, pp. 262, Hadees 6561)
