سَنُلْقِى فِى قُلُوبِ ٱلَّذِينَ كَفَرُوا۟ ٱلرُّعْبَ بِمَآ أَشْرَكُوا۟ بِٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَٰنًۭا ۖ وَمَأْوَىٰهُمُ ٱلنَّارُ ۚ وَبِئْسَ مَثْوَى ٱلظَّٰلِمِينَ
We shall cast terror into the hearts of those who disbelieve because they ascribe unto Allah partners, for which no warrant hath been revealed. Their habitation is the Fire, and hapless the abode of the wrong-doers.
