فَبَعَثَ اللَّهُ غُرابًا يَبحَثُ فِي الأَرضِ لِيُرِيَهُ كَيفَ يُواري سَوءَةَ أَخيهِ ۚ قالَ يا وَيلَتىٰ أَعَجَزتُ أَن أَكونَ مِثلَ هـٰذَا الغُرابِ فَأُوارِيَ سَوءَةَ أَخي ۖ فَأَصبَحَ مِنَ النّادِمينَ

Then Allah sent a crow searching in the ground to show him how to hide the disgrace of his brother. He said, "O woe to me! Have I failed to be like this crow and hide the body of my brother?" And he became of the regretful.
