سُورَةُ الأَنبِيَاءِ
Al-Anbiyaa·21:39
لَوْ يَعْلَمُ الَّذِينَ كَفَرُوا حِينَ لَا يَكُفُّونَ عَنْ وُجُوهِهِمُ النَّارَ وَلَا عَنْ ظُهُورِهِمْ وَلَا هُمْ يُنْصَرُونَ٣٩
If they but knew - they who are bent on denying the truth - [that there will come] a time when they will not be able to ward off the fire from their faces, nor from their backs, and will not find any succour!
