Surah 3. Aal-Imran
Ayah 153
153إِذْ تُصْعِدُونَ وَلَا تَلْوُۥنَ عَلَىٰٓ أَحَدٍ وَٱلرَّسُولُ يَدْعُوكُمْ فِىٓ أُخْرَىٰكُمْ فَأَثَـٰبَكُمْ غَمًّۢا بِغَمٍّ لِّكَيْلَا تَحْزَنُوا۟ عَلَىٰ مَا فَاتَكُمْ وَلَا مَآ أَصَـٰبَكُمْ ۗ وَٱللَّهُ خَبِيرٌۢ بِمَا تَعْمَلُونَ
[153] Recall how you were fleeing in such a panic that you did not even look back at one another, and the Messenger in your rear was calling nut to you.110 Consequently, Allah inflicted upon you one sorrow after the other111 so that you may learn this lesson for the that you should not grieve for what you have lost and for any misfortune that might befall you: Allah is fully aware of all that you are doing.
110It was the courage and firmness of the Holy Prophet that saved the situation from utter ruin in the confusion caused by the sudden attack of the enemy who was charging from the front and from the rear. When some of the Muslims were fleeing towards Al-Madinah and the others were climbing up the Uhd, the Holy Prophet stood firm and resolute at his post with a dozen or so of his Companions who had stood the test. He was rallying those who were taking to flight, calling out, "O servants of Allah, come to me."
111Sorrow was caused by the reverse and by the rumour that the Holy Prophet had been martyred and by the loss of their companions and by the misery of their wounded and by the insecurity of their homes and by the fear that the victorious Quraish army, that out-numbered the total population of Al-Madinah, would crush the routed army, enter into .the town and reduce it to ruins.
