"He will be given water of Sadid to drink, he will swallow it..." that the Prophet ﷺ said: " It will be brought toward his mouth and he will dislike it, so whenever it is brought closer to him it will melt his face and the skin of his head will fall into it. Then whenever he drinks from it, his bowels will be severed until it comes out from his anus. Allah, the Blessed and Exalted says: "And they will be given water of Hamim to drink such that it cuts up their bowels..." and He says: "And if they call for drink they will be given water of Muhl which melts the faces, the worst of drinks..."  

عَنِ النَّبِيِّ ﷺ فِي قَوْلِهِ (يُسْقَى مِنْ مَاءٍ صَدِيدٍ * يَتَجَرَّعُهُ ) قَالَ يُقَرَّبُ إِلَى فِيهِ فَيَكْرَهُهُ فَإِذَا أُدْنِيَ مِنْهُ شَوَى وَجْهَهُ وَوَقَعَتْ فَرْوَةُ رَأْسِهِ فَإِذَا شَرِبَهُ قَطَّعَ أَمْعَاءَهُ حَتَّى يَخْرُجَ مِنْ دُبُرِهِ يَقُولُ اللَّهُ (وَسُقُوا مَاءً حَمِيمًا فَقَطَّعَ أَمْعَاءَهُمْ ) وَيَقُولُ (وَإِنْ يَسْتَغِيثُوا يُغَاثُوا بِمَاءٍ كَالْمُهْلِ يَشْوِي الْوُجُوهَ بِئْسَ الشَّرَابُ )
