Psychological warfare and divine terror

سَنُلْقِى فِى قُلُوبِ ٱلَّذِينَ كَفَرُوا۟ ٱلرُّعْبَ بِمَآ أَشْرَكُوا۟ بِٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ سُلْطَـٰنًا ۖ وَمَأْوَىٰهُمُ ٱلنَّارُ ۚ وَبِئْسَ مَثْوَى ٱلظَّـٰلِمِينَ

We will cast terror into the hearts of those who disbelieve for what they have associated with Allāh of which He had not sent down [any] authority. And their refuge will be the Fire, and wretched is the residence of the wrongdoers.
