وَإِذْ يُرِيكُمُوهُمْ إِذِ الْتَقَيْتُمْ فِي أَعْيُنِكُمْ قَلِيلًا وَيُقَلِّلُكُمْ فِي أَعْيُنِهِمْ لِيَقْضِيَ اللَّهُ أَمْرًا كَانَ مَفْعُولًا وَإِلَى اللَّهِ تُرْجَعُ الْأُمُورُ

And when He showed them to you as few in your eyes, when you met them [on the battlefield], and He made you [appear] few in their eyes, [it was] in order that Allah may carry through a matter that was bound to be fulfilled, and to Allah all matters are returned.
