The case of Abel Cain is the first murder in the world

Abel and Cain were both sons of the original father, Adam.

The rule at that time was to give birth to children by force.One of them was a son and the other was a girl. At that time, it was the rule of Allah to give a sister of one marriage to a brother of another marriage.

Abel is older than Cain. When both of them reached the age of marriage, according to the rules, Abel's marriage with a relatively beautiful girl was decided.

But Cain did not agree to obey this rule, so the Prophet Adam (peace be upon him) ordered both of them to sacrifice for the sake of Allah Almighty.

If Allah had accepted it, He would have filled the sky with fire and then consumed it.

Otherwise he would have stayed in the field. According to the decision, Abel offered an excellent animal sacrifice. Cain offered a low quality grain.

A piece of fire came down from heaven and consumed Abel's sacrificed animal, but Cain's sacrificial grain remained in the field.

This proves that Abel's sacrifice was accepted in God's court.

After being defeated in the test of sacrifice, Kabil killed his brother in order to marry the beautiful girl.

Which is the first murder in human history.

Therefore, Cain will be responsible for the sins of all those who will be killed on earth.
