فَبَعَثَ اللَّهُ غُرَابًا يَبْحَثُ فِي الْأَرْضِ لِيُرِيَهُ كَيْفَ يُوَارِي سَوْءَةَ أَخِيهِ قَالَ يَاوَيْلَتَا أَعَجَزْتُ أَنْ أَكُونَ مِثْلَ هَذَا الْغُرَابِ فَأُوَارِيَ سَوْءَةَ أَخِي فَأَصْبَحَ مِنَ النَّادِمِينَ

Then Allah sent a crow, exploring in the ground, to show him how to bury the corpse of his brother. He said, ‘Woe to me! Am I unable to be [even] like this crow and bury my brother’s corpse?’ Thus he became regretful.
