Cain killed his brother Abel, so Abel perished, while Cain's seed continued as the present people: Children of Adam.
The parable of the two sons of Adam:
Cain envied his brother Abel because ِAbel's fiancée was more beautiful than the fiancée of Cain; so the consequence was that Cain turned to be a loser in his life of the World, and in addition he lost the reward of the Next Life, because of the envy which led him to kill his brother; although his brother did not do him any offense.
While his brother Abel gained the good reputation in the life of the World and the prosperity in the Next Life, on account of his piety and God-fearing.
Quran 5: 27, which means:
([Mohammed,] recite to the [Jews] the story of the two sons of Adam with [expounding] the truth; how they offered [each] an offering; and it was accepted of one of them, and not accepted of the other.
Said [Cain to his brother Abel]: "I will surely kill you."
Said [Abel]: "God does accept only from those who ward off [His disobedience.])

The implication of this parable in the Quran:
Jews envied Prophet Mohammed, because he became the prophet out of the Arab, not out of the Jews .. and the revelation was curtailed from them, and God stopped to reveal to them or make any prophet out of them.
This envy led the Jews at the time of Prophet Mohammed to reject him and to become his enemy and adversary: for why should the revelation not come to them, but it came to the Arab !! .. and the revelation should be confined to them alone exclusively.
So this was like the envy of Satan to Adam, and like the envy of Cain to his brother Abel.
