Abel is a figure from the Book of Genesis in the Hebrew Bible and the Quran, the second son of Adam and Eve and the younger brother of Cain. The name Abel is derived from the Hebrew name Hebel (הֶבֶל), which means "breath," "vanity," or "vapor." In Arabic, he is known as Habil (حَابِل). In the biblical narrative, Abel is a shepherd who offers a sacrifice to God that is accepted, while his brother Cain, a farmer, offers a sacrifice that is not. Cain's jealousy leads him to murder Abel, making Abel the first victim of homicide in the biblical tradition. This story is significant in both Jewish and Christian theology, as it explores themes of jealousy, sacrifice, and divine favor. The story of Cain and Abel is also referenced in the Quran, where it serves as a cautionary tale about the consequences of envy and violence.
