153rd Ayah from Surah Al 'Imran
Sahih International
[Remember] when you [fled and] climbed [the mountain] without looking aside at anyone while the Messenger was calling you from behind. So Allah 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 Allah is [fully] Acquainted with what you do.
Abdul Haleem
You fled without looking back while the Messenger was calling out to you from behind, and God rewarded you with sorrow for sorrow. [He has now forgiven you] so that you may not grieve for what you missed or for what happened to you. God is well aware of everything you do.
Mohsin Khan/Hilali
(And remember) when you ran away (dreadfully) without even casting a side glance at anyone, and the Messenger (Muhammad SAW) was in your rear calling you back. There did Allah 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 Allah is Well-Aware of all that you do.
Taqi Usmani
When you were going away, not even turning to look at anyone, and the Messenger was calling you from behind you. He awarded you sorrow for sorrow, so that you should not grieve (in future) over what you lost, or for what you suffered. Allah is All-Aware of what you do.
