Hagar

According to the Book of Genesis, Hagar is an Egyptian slave, a handmaiden of Sarah, whom Sarah gave to her own husband Abram as a wife to bear him a child. Abraham's firstborn son through Hagar, Ishmael, became the progenitor of the Ishmaelites, generally taken to be the Arabs. Various commentators have connected her to the Hagrites, perhaps claiming her as their eponymous ancestor. Hagar is alluded to, although not named, in the Quran, and Islam considers her Abraham's second wife.
