Al 'Imran, 166 Ayah
3:166
وَمَآ أَصَٰبَكُمۡ يَوۡمَ ٱلۡتَقَى ٱلۡجَمۡعَانِ فَبِإِذۡنِ ٱللَّهِ وَلِيَعۡلَمَ ٱلۡمُؤۡمِنِينَ ١٦٦
Wa Mā 'Aşābakum Yawma At-Taqá Al-Jam`āni Fabi'idhni Al-Lahi Wa Liya`lama Al-Mu'uminīna
And what struck you on the day the two armies met was by permission of Allah that He might make evident the [true] believers.
