The story is that Cain was roughness and intensity in his nature, while Abel had a softness of paper, and Cain was working in agriculture, while Abel worked in sheep grazing. This issue required mercy and passion for animals. Humanity needed a different law to breed. Today, it is forbidden to marry a sister, but Adam's time, it was different.
At the time, Kabil married any of his sisters except the twins who were born with him. As well as Abel, he was allowed to marry any of his sisters except the twins. Abel's sister was close to him, but she was less beautiful than Cain's sister. Cain did not like to marry his beautiful sister to his brother and he wanted to marry her, but that was haraam and Adam stressed that. Adam was a prophet with legal and laws.
Cain was angry with the law of Adam, and there was the law of offering the offerings, which was a gift to God Almighty. It is a sacrifice distributed to the poor or birds. They had a sign of accepting the Eucharist, which is that it is eaten by fire, and the one that is not eaten by fire is unacceptable (i.e., a lightning
On the day of offering the offerings, Abel chose the best livestock he has and offered him an offering to God Almighty. As for Cain, he came with a stinking and sacrifice. When they came on the second day, they found that the offering of Abel had been accepted and the offering of Cain was untouched by the fire, so Cain's anger
The first murder in human history
Cain went to Abel and said, "I will kill you." Abel replied to him, and said, "If he kill him, he will not kill him, and he will not defend, and you will be with your sins that you do, you will increase in the tedness of killing me and you will bear him. Indeed, on a black night while Abel was sleeping, Cain came with a rock and his brother's head shattered it.
Cain was confused what to do with his brother because it was the first time a human being died, then he carried Abel's body on his back and started walking and didn't know what to do? While he is, when God Almighty sent down crows, and the crows fought each other, and the crow died before the sight of Cain, then the living crow began digging with dirt, pushing the dead crow and pushing the dust on him. Cain learned from the dust how to bury his brother, so he dug into the ground and put
Cain became regretful how he did this and did not ask forgiveness from God Almighty, and repentance requires asking forgiveness from God Almighty.
The story is mentioned in Surat Al-Ma'ida: "And recite to them the news of my son Adam with the truth when he approached an offering, so he accepted from one of them and did not accept from the other. He said, "I will kill you." He said, "God only accepts from the righteous." (27) If you extend your hand to me He became one of the regrets (31)."
Cain escapes with his wife away from Adam
After Cain killed Abel, Adam fled his father, took his wife, and lived in the plains. Adam lived near the mountains.
Cain was cut off from Adam and his descendants began to breed, and obscenities spread among them, and they did not worship God, but they violated the teachings that Adam says, and corruption was resolved in the children of Cain.
And the people were divided into the people of evil, what Cain and the people of goodness lived with Adam and his sons. Adam lived 960 years and was a thousand years old, but he took 40 years in many prophetic hadiths. It is true that when God created Adam, he wiped his back, and fell from his back every breath, the creator of Adam until My Lord said and how old did you make his life? Sixty years ago, he said, "My Lord, increase my age by 40 years, God is able to do so." When Adam's life passed, the king of death came to him and said to the king of death, "Is not 40 years of me left?" He said, "Didn't you give it to your son David?" The Messenger of Allah (may Allah's peace and blessings be upon him) said, so he disbelieved, and his offspring disbelieved, and he forgot his offspring and Adam's mistake, and his offspring sin sinned." That is, Adam did not do it intentionally, but he forgot, so he was called "Man" because he is very forgetful.
