When you ran off precipitately and did not wait for any one, and the Messenger was calling you from your rear, so He gave you another sorrow instead of (your) sorrow, so that you might not grieve at what had escaped you, nor (at) what befell you; and Allah is aware of what you do.

So their Lord accepted their prayer: That I will not waste the work of a worker among you, whether male or female, the one of you being from the other; they, therefore, who fled and were turned out of their homes and persecuted in My way and who fought and were slain, I will most certainly cover their evil deeds, and I will most certainly make them enter gardens beneath which rivers flow; a reward from Allah, and with Allah is yet better reward.

And those who were given the knowledge said: Woe to you! Allah's reward is better for him who believes and does good, and none is made to receive this except the patient.
