مِّن وَرَايِهِ جَهَنَّمُ
In front of him is Hell,
Allah says that Jahannam is in front of every obstinate tyrant, awaiting him, and he will reside in it forever on the Day of Return. He will be brought to it in the morning and the afternoon until the Day of the Call,
وَيُسْقَى مِن مَّاء صَدِيدٍ
and he will be made to drink boiling, festering water.
in the Fire, his only drink will be from Hamim and Ghassaq, the former is very hot and the latter is very cold and rotten.
Allah said in another instance,
هَـذَا فَلْيَذُوقُوهُ حَمِيمٌ وَغَسَّاقٌ
وَءَاخَرُ مِن شَكْلِهِ أَزْوَجٌ
This is so! Then let them taste it - Hamim and Ghassaq. And other (torments) of similar kind all together! (38;57-58)
Mujahid and Ikrimah said that;
this festering water is made of puss and blood.
Allah said in other Ayat,
وَسُقُواْ مَأءً حَمِيماً فَقَطَّعَ أَمْعَأءَهُمْ
And be given to drink boiling water so that it cuts up their bowels. (47;15)
and,
وَإِن يَسْتَغِيثُواْ يُغَاثُواْ بِمَأءٍ كَالْمُهْلِ يَشْوِى الْوجُوهَ
And if they ask for help, they will be granted water like boiling oil, that will scald their faces. (18;29)
