Dr. Mustafa Khattab, the Clear Quran - Surah Ali 'Imran, ayah 166

Translation of Surah Ali 'Imran, ayah 166 (3:166)

وَمَآ أَصَٰبَكُمۡ يَوۡمَ ٱلۡتَقَى ٱلۡجَمۡعَانِ فَبِإِذۡنِ ٱللَّهِ وَلِيَعۡلَمَ ٱلۡمُؤۡمِنِينَ ١٦٦
So what you suffered on the day the two armies met was by Allah’s Will, so that He might distinguish the ˹true˺ believers
