﴿ فَبَعَثَ ٱللَّهُ غُرَابًۭا يَبْحَثُ فِى ٱلْأَرْضِ لِيُرِيَهُۥ كَيْفَ يُوَٰرِى سَوْءَةَ أَخِيهِ ۚ قَالَ يَٰوَيْلَتَىٰٓ أَعَجَزْتُ أَنْ أَكُونَ مِثْلَ هَٰذَا ٱلْغُرَابِ فَأُوَٰرِىَ سَوْءَةَ أَخِى ۖ فَأَصْبَحَ مِنَ ٱلنَّٰدِمِينَ ﴾

“Thereupon God sent forth a raven which scratched the earth, to show him how he might conceal the nakedness of his brother's body. [And Cain] cried out: "Oh, woe is me! Am I then too weak to do what this raven did, and to conceal the nakedness of my brother's body?" - and was thereupon smitten with remorse.”

Then God sent forth a raven scratching into the earth digging up the soil with its beak and with its legs and throwing it up over a dead raven next to it until it completely hid it to show him how he might hide the nakedness the carcass of his brother. He said ‘Woe to me! Am I not able to be as this raven and so hide my brother’s nakedness?’ And he became one of the remorseful for having carried him; he then dug a hole for him and covered him up.
