Allah the Almighty says:
{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;
when each offered a sacrifice (to Allah), it was accepted from the one
but not from the other. The latter said to the former: "I will surely kill
you." The former said: "Verily, Allah accepts only from those who are
Al-Muttaqun (the pious)." "If you do stretch your hand against me to
kill me, I shall never stretch my hand against you to kill you: for I fear
Allah, the Lord of the `Alamin (mankind, jinn, and all that exists)."
"Verily, I intend to let you draw my sin on yourself as well as yours,
then you will be one of the dwellers of the Fire; and that is the
recompense of the Zalimin (polytheists and wrong-doers);" 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)
