Quran 8:44 Al-Anfal, ayah 44 of 75

وَإِذْ يُرِيكُمُوهُمْ إِذِ ٱلْتَقَيْتُمْ فِىٓ أَعْيُنِكُمْ قَلِيلًا وَيُقَلِّلُكُمْ فِىٓ أَعْيُنِهِمْ لِيَقْضِىَ ٱللَّهُ أَمْرًا كَانَ مَفْعُولًا ۗ وَإِلَى ٱللَّهِ تُرْجَعُ ٱلْأُمُورُ ۝٤٤

8:44 And when He made you (Muslims), when ye met (them), see them with your eyes as few, and lessened you in their eyes, (it was) that Allah might conclude a thing that must be done. Unto Allah all things are brought back.
