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»

(Hell will be brought forth on the Day of Resurrection, pulled by means of seventy thousand reins, each of which will be held by seventy thousand angels.) Then Allah says of them:

الَّذِينَ كَانَتْ أَعْيُنُهُمْ فِى غِطَآءٍ عَن ذِكْرِى

((To) those whose eyes had been under a covering from My Reminder,) meaning, they neglected it, turning a blind eye and a deaf ear to it, refusing to accept guidance and follow the truth. As Allah says:

وَمَن يَعْشُ عَن ذِكْرِ الرَّحْمَـنِ نُقَيِّضْ لَهُ شَيْطَاناً فَهُوَ لَهُ قَرِينٌ

(And whosoever turns away blindly from the remembrance of the Most Gracious, We appoint for him a Shaytan to be a companion for him.) 43:36 And here Allah says:

وَكَانُواْ لاَ يَسْتَطِيعُونَ سَمْعاً

(and they could not bear to hear (it). ) meaning, they did not understand the commands and prohibitions of Allah. Then He says:

أَفَحَسِبَ الَّذِينَ كَفَرُواْ أَن يَتَّخِذُواْ عِبَادِى مِن دُونِى أَوْلِيَآءَ

(Do then those who disbelieved think that they can take My servants as Awliya' protectors besides Me) meaning, do they think that this is right for them and that it is going to benefit them

كَلاَّ سَيَكْفُرُونَ بِعِبَـدَتِهِمْ وَيَكُونُونَ عَلَيْهِمْ ضِدّاً

(Nay, but they will deny their worship of them, and become opponents to them) 19:82. Allah says that He has prepared Hell as their abode on the Day of Resurrection.
