5:31Then God sent a raven digging the ground, to show him how to cover his brother's corpse. He said, “Woe to me! I was unable to be like this raven, and bury my brother's corpse.” So he became full of regrets.

5:52You will see those in whose hearts is sickness racing towards them. They say, “We fear the wheel of fate may turn against us.” But perhaps God will bring about victory, or some event of His making; thereupon they will regret what they concealed within themselves.
