3:140If a wound afflicts you, a similar wound has afflicted the others. Such days We alternate between the people, that God may know those who believe, and take martyrs from among you. God does not love the evildoers.

3:146How many a prophet fought alongside him numerous godly people? They did not waver for what afflicted them in the cause of God, nor did they weaken, nor did they give in. God loves those who endure.

3:153Remember when you fled, not caring for anyone, even though the Messenger was calling you from your rear. Then He repaid you with sorrow upon sorrow, so that you would not grieve over what you missed, or for what afflicted you. God is Informed of what you do.
