وَالَّذِينَ كَفَرُواْ لَهُمْ شَرَابٌ مِّنْ حَمِيمٍ وَعَذَابٌ أَلِيمٌ بِمَا كَانُواْ يَكْفُرُونَ
(But those who disbelieved will have a drink of boiling fluids and painful torment because they used to disbelieve.) meaning, because of their disbelief they will be punished on the Day of Resurrection by different forms of torment, such as fierce hot winds, boiling water, and the shadow of black smoke.
