Az-Zumar 39:19

Afaman haqqa AAalayhi kalimatu alAAathabiafaanta tunqithu man fee annar

Then, is one who has deserved the decree of punishment [to be guided]? Then, can you save one who is in the Fire?

So tell Me about the one for whom the word of punishment is destined, - is it you, then, who would save someone who is already in the Fire?
