Aal-i-Imraan 3:153

[Remember] when you were fleeing without even casting a glance at anyone, and the Messenger was calling you back. You were then given distress[69] upon distress, so you should not grieve for what you missed or for what you suffered. For Allah is All-Aware of what you do.

[69] The news of the rumored death of the Prophet (ﷺ) hit them after losing the ground in the battle, so they soon forgot the defeat that had been inflicted on them.

[Remember] when you [fled and] climbed [the mountain] without looking aside at anyone while the Messenger was calling you from behind. So Allāh repaid you with distress upon distress so you would not grieve for that which had escaped you [of victory and spoils of war] or [for] that which had befallen you [of injury and death]. And Allāh is [fully] Aware of what you do.

153. (And remember) when you ran away (dreadfully) without even casting a side glance at anyone, and the Messenger (Muhammad صلى الله عليه وسلم) was in your rear calling you back. There did Allâh give you one distress after another by way of requital to teach you not to grieve for that which had escaped you, nor for that which had befallen you. And Allâh is Well-Aware of all that you do.

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.
