And what struck you on the day the two armies met was (3:166)

﴿وَمَا أَصَابَكُمْ يَوْمَ الْتَقَى الْجَمْعَانِ فَبِإِذْنِ اللَّهِ وَلِيَعْلَمَ الْمُؤْمِنِينَ﴾
[ آل عمران: 166]

3:166 And what struck you on the day the two armies met was by permission of Allah that He might make evident the [true] believers.

The death, wounds and defeat you suffered on the day of Uḥud, when your army and the army of the idolaters met, was by the permission and decree of Allah, with far-reaching wisdom behind it: to make it clear who truly had faith.

And what you suffered (of the disaster) on the day (of the battle of Uhud when) the two armies met, was by the leave of Allah, in order that He might test the believers.
