Kal Muhl, the Prophet ﷺsaid: 'Like boiling oil, such that when it is brought close to his face, the skin of his face will fall off into it."  

عَنِ النَّبِيِّ ﷺ فِي قَوْلِهِ (كَالْمُهْلِ ) قَالَ كَعَكَرِ الزَّيْتِ فَإِذَا قَرَّبَهُ إِلَى وَجْهِهِ سَقَطَتْ فَرْوَةُ وَجْهِهِ فِيهِ  

Indeed Hamim will be poured over their heads. The Hamim will penetrate until it finds its way to his insides. Then whatever is inside him will fall out until it pours over his feet while it melts away. Then he will be reformed to how he was."  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّ الْحَمِيمَ لَيُصَبُّ عَلَى رُءُوسِهِمْ فَيَنْفُذُ الْحَمِيمُ حَتَّى يَخْلُصَ إِلَى جَوْفِهِ فَيَسْلِتَ مَا فِي جَوْفِهِ حَتَّى يَمْرُقَ مِنْ قَدَمَيْهِ وَهُوَ الصَّهْرُ ثُمَّ يُعَادُ كَمَا كَانَ وَسَعِيدُ بْنُ يَزِيدَ يُكْنَى أَبَا شُجَاعٍ وَهُوَ مِصْرِيٌّ وَقَدْ رَوَى عَنْهُ اللَّيْثُ بْنُ سَعْدٍ  

"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 )  

Kal Muhl, the Prophet ﷺ said: "Like boiling oil, such that whenever it is brought near him the skin of his face falls into it." And also with this chain, from the is Prophet SAW, that he said: "If a bucket of Ghassaq were poured out in the world, the people of the world would rot. (Da'if) And the meaning of his statement: "The Kithaf of each wall" is its thickness.  

عَنِ النَّبِيِّ ﷺ قَالَ (كَالْمُهْلِ ) كَعَكَرِ الزَّيْتِ فَإِذَا قُرِّبَ إِلَيْهِ سَقَطَتْ فَرْوَةُ وَجْهِهِ فِيهِ وَبِهَذَا الإِسْنَادِ عَنِ النَّبِيِّ ﷺ قَالَ لِسُرَادِقِ النَّارِ أَرْبَعَةُ جُدُرٍ كِثَفُ كُلِّ جِدَارٍ مِثْلُ مَسِيرَةِ أَرْبَعِينَ سَنَةً وَبِهَذَا الإِسْنَادِ عَنِ النَّبِيِّ ﷺ قَالَ لَوْ أَنَّ دَلْوًا مِنْ غَسَّاقٍ يُهَرَاقُ فِي الدُّنْيَا لأَنْتَنَ أَهْلُ الدُّنْيَا  

Have the Taqwa of Allah as His due, and do not die except as Muslims. And the Messenger of Allah ﷺ said: "If only a drop of Az-Zaqqum were to drip into the abode of the world, it would spoil the peoples' livelihood, so how about the person for whom it is his food?"  

أَنَّ رَسُولَ اللَّهِ ﷺ قَرَأَ هَذِهِ الآيَةَ (اتَّقُوا اللَّهَ حَقَّ تُقَاتِهِ وَلاَ تَمُوتُنَّ إِلاَّ وَأَنْتُمْ مُسْلِمُونَ ) قَالَ رَسُولُ اللَّهِ ﷺ لَوْ أَنَّ قَطْرَةً مِنَ الزَّقُّومِ قُطِرَتْ فِي دَارِ الدُّنْيَا لأَفْسَدَتْ عَلَى أَهْلِ الدُّنْيَا مَعَايِشَهُمْ فَكَيْفَ بِمَنْ يَكُونُ طَعَامَهُ
