Surah Al-Anbiyaلَوۡ يَعۡلَمُ ٱلَّذِينَ كَفَرُواْ حِينَ لَا يَكُفُّونَ عَن وُجُوهِهِمُ ٱلنَّارَ وَلَا عَن ظُهُورِهِمۡ وَلَا هُمۡ يُنصَرُونَ
Had those who do not believe but known the time when they will not be able to stop the fire from their faces and from their backs and they will not be helped (they would not have asked you such a question)
