Adam (Peace be upon him) was. the father of mankind.

Allah, the Almighty says: {It is He Who has created you from a single person (Adam), and (then) He has created from him his wife ..

.. [Hawwa' (Eve)], in order that he might enjoy the pleasure of living with her. When he had sexual relation with her, she became pregnant

Imam Abu J a’ far mentioned in his Tarikh “History” on the authority of people who said: Eve gave birth to 40 children through 20 births.

Others said: there were one hundred and twenty births, in each one a male and a female were born.

The first among them were Cain and his sister Qalimah, and the last ones were `Abdul Mughith and his sister Ummul Mughith.

{And (O Muhammad (Peace be upon him» recite to them (the Jews) the story of the two sons of Adam (Habil and Qabil) in truth

Adam (Peace be upon him) used to get the male brought by one birth married to the female brought by the other.

Hence, it was supposed that Abel would get married to Cain’s sister who was better and more beautiful than anyone else.

At the same time, Cain wanted to keep her for himself.

Adam (Peace be upon him) ordered him to allow’ Abel to marry her, but he totally refused.

Then, Adam (Peace be upon him) ordered both (Abel and Cain) to offer a sacrifice to Allah Almighty.

Meanwhile, Adam set forth towards Mecca to perform Pilgrimage. Just before leaving, Adam tried to entrust (the affairs of) his children ...

.. to the heavens, the earth and finally to the mountains, but all declined to shoulder the (heavy) trust.

Thereupon, Cain accepted the trust and after Adam went away they (Abel and Cain) offered their sacrifices to Allah.

Abel offered a fat she-goat, while Cain offered a bundle of bad plants. Later, a fire came down from heaven ...

...and consumed the sacrifice offered by Abel and left untouched that of Cain.

Cain became livid with rage and said to his brother: I will kill you so as not to marry my sister, Abel said: {Verily, Allah accepts

only from those who are Al-Muttaqun (the pious)}.

So the Nafs (self) of the other (latter one) encouraged him and made fair-seeming to him the murder of his brother;

he murdered him and became one of the losers;

Then Allah 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

(Al–Ma’idah, 27-31)
