The Thunder - 13:5 "If you wonder, wonder at their saying: "Shall we be created again after we have become dust?"Those are they who disbelieve in their Lord. They are the ones who deserve shackles around their necks. They are the inhabitants of the Fire, wherein they will abide forever."
They will remain in Hell forever:
Prophet Hud/11:106 The unfortunate are in the Fire. They will groan therein.
Prophet Hud/11:107 They will abide therein as long as the heavens and the earth endure, except if your Lord wills. Your Lord is the Doer of whatever He wills

Prophet Abraham/14:17 He will try to swallow it, but he will not be able to choke it down. Death will come to him from all sides, but he will not die. And a severe torment will follow.

Originator/35:36 For those who disbelieve is the Fire of Hell. They will not be allowed to die, nor will the punishment of Hell be lightened for them. This is how We punish the ungrateful.

The Ornaments of Gold/43:77 "They call out, "O Malik, let your Lord finish us". He says: "You will remain like this"."
