۞ إِذْ تُصْعِدُونَ وَلَا تَلْوُۥنَ عَلَىٰٓ أَحَدٍ وَٱلرَّسُولُ يَدْعُوكُمْ فِىٓ أُخْرَٮٰكُمْ فَأَثَـٰبَكُمْ غَمَّۢا بِغَمٍّ لِّكَيْلَا تَحْزَنُواْ عَلَىٰ مَا فَاتَكُمْ وَلَا مَآ أَصَـٰبَكُمْۗ وَٱللَّهُ خَبِيرُۢ بِمَا تَعْمَلُونَ ١٥٣
When ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do.
