Accoring to Genesis, Cain and Abel were the first and second sons of Adam and Eve, born after the Fall of Man. Their story is told in Genesis 4:1-16, the Qur'an at 5:26-32, and Moses 5:16-41. In all versions, Cain, a farmer, commits the first murder by killing his brother Abel, a shepherd, after God (called YHWH) rejects Cain's sacrifice but accepts Abel's.
