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
If the disbelievers only knew, the time will arrive when they will not be able to ward off the Fire from their faces or their backs, and they will get no help.
If only those who deny knew the moment when they will not be able to keep the fire from their faces or their backs, and no help will come to them.
