Abraham's first son was Yishmael, born from his second wife Hagar. However, G-d rejected Yishmael as the future of Abraham's movement. Later Abraham was forced to send Yishmael away and he fell into an unholy life. Today many people (mostly Arabs) claim to be descendants of Yishmael.

What do our Jewish traditions say about Yishmael? What does he represent in Judaism?
