Why was the raven specifically mentioned in the story of Adam's two sons to teach the killer how to bury his brother, and what is the wisdom behind that?

God did not present any parable in the Quran except for a wisdom. Among these is the story of the crow that God sent to teach the son of Adam how to bury the dead. The crow was chosen for this either because it instinctively buries, or due to the suitability of its black color to the contraction that afflicts the soul, or because it is considered a bad omen in separation, and by its nature, it searches the earth. It is wise for a Muslim to learn from everything around them. For the stories of the Quran are admonitions and lessons for the believer.
