Al-Anbiyaa 21:39

لَوْ يَعْلَمُ ٱلَّذِينَ كَفَرُوا۟ حِينَ لَا يَكُفُّونَ عَن وُجُوهِهِمُ ٱلنَّارَ وَلَا عَن ظُهُورِهِمْ وَلَا هُمْ يُنصَرُونَ

Law ya'lamul lazeena kafaroo heena laa yakuffoona 'anw wujoohihimun Naara wa laa 'an zuhoorihim wa laa hum yunsaroon

Had those who disbelieve but known (of the time) when they shall not be able to ward off the fire from their faces nor from their backs, nor shall they be helped.
