How will the people of the Hell be tortured?

{ These1 are two adversaries who have disputed over their Lord. But those who disbelieved will have cut out for them garments of fire. Poured upon their heads will be scalding water  By which is melted that within their bellies and [their] skins. And for [striking] them are maces of iron. Every time they want to get out of it [i.e., Hellfire] from anguish, they will be returned to it, and [it will be said], "Taste the punishment of the Burning Fire!" }
