The Glorious Quran mentions the torments that will cause to Hell-dwellers at different places:

اِنَّاۤ اَعۡتَدۡنَا لِلظّٰلِمِیۡنَ نَارًا ۙ اَحَاطَ بِہِمۡ سُرَادِقُہَا ؕ وَ اِنۡ یَّسۡتَغِیۡثُوۡا یُغَاثُوۡا بِمَآءٍ کَالۡمُہۡلِ یَشۡوِی الۡوُجُوۡہَ ؕ بِئۡسَ الشَّرَابُ ؕ وَ سَآءَتۡ  مُـرۡتَفَقًا ﴿۲۹﴾

Translation from Kanz-ul-Iman: And proclaim, ‘The Truth is from your Lord’; so whoever wills may accept faith, and whoever wills may disbelieve - We have indeed prepared for the disbelievers a fire the walls of which will surround them; if they plead for water, their plea will be answered with water like molten metal which shall scald their faces; what an evil drink it is; and what an evil destination is Hell! (Part 15, Surah Al-Kahf, verse 29)

It is stated at another place in Glorious Quran:

فَالَّذِیۡنَ کَفَرُوۡا قُطِّعَتۡ لَہُمۡ ثِیَابٌ مِّنۡ نَّارٍ ؕ یُصَبُّ مِنۡ فَوۡقِ رُءُوۡسِہِمُ الۡحَمِیۡمُ ﴿ۚ۱۹﴾   یُصۡہَرُ  بِہٖ  مَا فِیۡ  بُطُوۡنِہِمۡ  وَ الۡجُلُوۡدُ ﴿ؕ۲۰﴾   وَ لَہُمۡ  مَّقَامِعُ مِنۡ  حَدِیۡدٍ ﴿۲۱﴾  کُلَّمَاۤ  اَرَادُوۡۤا اَنۡ یَّخۡرُجُوۡا مِنۡہَا مِنۡ غَمٍّ  اُعِیۡدُوۡا فِیۡہَا ٭ وَ ذُوۡقُوۡا عَذَابَ الۡحَرِیۡقِ ﴿٪۲۲﴾

Translation from Kanz-ul-Iman: So those who disbelieved – garments of fire have been fashioned for them; and boiling water will be poured onto their heads. With which will melt what is in their bellies, and their skins. And for them are rods of iron. Whenever they wish to come out of it due to suffocation, they will be returned to it again and it will be commanded, "Taste the punishment of fire!" (Part 17, Surah Al-Hajj, verse 19 to 22)

Dear Islamic brothers! You have just heard how admonitory treatment will be meted out to hell-dwelling people and they will face such extremely painful torments in the hell. Our Beloved Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم, for teaching us,
