Al-Maaida 5:31

Then Allah sent a crow scratching the ground[27] to show him how to bury the corpse of his brother. He said, “Woe to me! Have I failed even to be like this crow to bury the corpse of my brother?” And he became one of the remorseful.

[27] It is said that this raven was burying another of its kind.

Then Allāh sent a crow searching [i.e., scratching] in the ground to show him how to hide the disgrace[257] of his brother. He said, "O woe to me! Have I failed to be like this crow and hide the disgrace [i.e., body] of my brother?" And he became of the regretful.

[257] Referring to the dead body, evidence of his shameful deed.

31. Then Allâh sent a crow who scratched the ground to show him to hide the dead body of his brother. He (the murderer) said: "Woe to me! Am I not even able to be as this crow and to hide the dead body of my brother?" Then he became one of those who regretted.

Then Allah sent a raven scratching up the ground, to show him how to hide his brother's naked corpse. He said: Woe unto me! Am I not able to be as this raven and so hide my brother's naked corpse? And he became repentant.
