Arabic Folklore Cain and Abel The Sons of Prophet Adam (Pbuh) and The Crow Birds

Time changes everything. People's hair turns white as they grow older, but one thing always stays the same, the feathers of the crow that never change color. If anyone experienced what we, the crows, had experienced, his hair would never turn white.
As a creature I was the only eyewitness to the first crime of murder committed on the earth. I witnessed the first drop of human blood that was shed treacherously. I also knew that Allah was witnessing it all.
It was a very terrifying day. I knew that it was all due to Satan. How strange the actions of Satan are! How compliant human beings are to him! People love Allah SWT (God), yet they disobey Him and while they hate Satan, they obey him. How strange the species called "humans" and how grave his contradictions are! How great Allah's mercy and forgiveness is to man! Excuse my language for I am a little bit angry.
When people experience hard times they have a saying that goes: "They were days blacker than the crow's feathers." I am aware that the crow's black color irritates people but they are oblivious to the fact that even the blackest feather on the crow's body is nothing compared to the human heart when it grows black because of sin.
I also know that people make fun of the way a crow walks, for he hops around when he walks like a mad person walking on firebrand. He is always on the move.
So, let us assume that we walk in a strange way -hopping and leaping about. Is that not considered natural after we have witnessed the injustice inflicted by a human being upon his brother?
Before the human being was created, we used to walk about with a swinging gait like that of kings. We were proud of our black color. Then, we witnessed a brother killing his brother and from that time onward our walk has become disturbed due to the horror of the act and our children inherited our handicap.
