Psychological warfare and perception

وَإِذْ يُرِيكُمُوهُمْ إِذِ ٱلْتَقَيْتُمْ فِىٓ أَعْيُنِكُمْ قَلِيلًا وَيُقَلِّلُكُمْ فِىٓ أَعْيُنِهِمْ لِيَقْضِىَ ٱللَّهُ أَمْرًا كَانَ مَفْعُولًا ۗ وَإِلَى ٱللَّهِ تُرْجَعُ ٱلْأُمُورُ

And [remember] when He showed them to you, when you met, as few in your eyes, and He made you [appear] as few in their eyes so that Allāh might accomplish a matter already destined. And to Allāh are [all] matters returned.
