Hell will be displayed before the Disbelievers on the Day of Resurrection

Allah tells us what He will do to the disbelievers on the Day of Resurrection. He will show Hell to them, meaning He will bring it forth for them to see its punishment and torment before they enter it. This will intensify their distress and grief. In Sahih Muslim it is recorded that Ibn Mas`ud said, "The Messenger of Allah ﷺ said,

«يُؤْتَى بِجَهَنَّمَ تُقَادُ يَوْمَ الْقِيَامَةِ بِسَبْعِينَ أَلْفَ زِمَامٍ، مَعَ كُلِّ زِمَامٍ سَبْعُونَ أَلْفَ مَلَك»

Commentary

As for the pronoun of the word: بَعْضَهُمْ (ba` dahum) in بَعْضَهُمْ يَوْمَئِذٍ يَمُوجُ فِي بَعْضٍ (And on that day, We will leave them [ Ya’ juj and Ma'juj ] surging over one another - 99), it is obvious that it reverts back to Ya'juj Ma juj. Then, as for their condition described therein - 'surging over one another' - it is also obvious that this will be their state when the passage lies open for them and they will be hastening their way from the hilly heights down to the ground. Commentators have suggested other probabilities as well.
