It's jahannam ("a dark storm" or "a stern expression" or a kind of "hell-fire") in the Qu'ran:

"...fear the Fire whose fuel is men and stones,- which is prepared for those who reject Faith" (2:24).

"...Enough is Hell for a burning fire. Those who reject Our Signs, We shall soon cast into the Fire... For Allah is Exalted in Power, Wise" (4:55-56).

"But he whose balance (of good deeds) is found to be light, will have his home in a (bottomless) Pit. And what will explain to you what this is? A Fire blazing fiercely!" (101:8-11). 

"Those who reject Faith, and die rejecting,- on them is Allah's curse, and the curse of angels, and of all mankind. They will abide therein: Their penalty will not be lightened, nor will they receive respite" (2:161-162).

"They are (men) whom Allah hath cursed: And those whom Allah Hath cursed, thou wilt find, have no one to help" (4:52).
