In Abrahamic traditions

According to Arab– Islamic–Jewish traditions, Ishmael, the son of Abraham and Hagar was "father of the Arabs". The Book of Genesis narrates that God promised Hagar to beget from Ishmael twelve princes and turn his descendants into a " great nation". Ishmael was considered the ancestor of the Islamic prophet Muhammad, the founder of Islam. The tribes of Central West Arabia called themselves the "people of Abraham and the offspring of Ishmael." Ibn Khaldun, an Arab scholar in the 8th century, described the Arabs as having Ishmaelite origins.

The Quran mentions that Ibrahim (Abraham) and his wife Hajar (Hagar) bore a prophetic child named Ishmael, who was gifted by God a favor above other nations. God ordered Ibrahim to bring Hajar and Ishmael to Mecca, where he prayed for them to be provided with water and fruits. Hajar ran between the hills of Safa and Marwa in search of water, and an angel appeared to them and provided them with water. Ishmael grew up in Mecca. Ibrahim was later ordered to sacrifice Ishmael in a dream, but God intervened and replaced him with a goat. Ibrahim and Ishmael then built the Kaaba in Mecca, which was originally constructed by Adam.

According to the Samaritan book Asaṭīr adds: "And after the death of Abraham, Ishmael reigned twenty-seven years; And all the children of Nebaot ruled for one year in the lifetime of Ishmael; And for thirty years after his death from the river of Egypt to the river Euphrates; and they built Mecca." Josephus also lists the sons and states that they "...inhabit the lands which are between Euphrates and the Red Sea, the name of which country is Nabathæa. The Targum Onkelos annotates (Genesis 25:16), describing the extent of their settlements: The Ishmaelites lived from Hindekaia (India) to Chalutsa (possibly in Arabia), by the side of Mizraim (Egypt), and from the area around Arthur (Assyria) up towards the north. This description suggests that the Ishmaelites were a widely dispersed group with a presence across a significant portion of the ancient Near East.
