The tribes of Arabia are the clans that originated in the Arabian Peninsula.

According to Arab tradition, the Adnanites are called Arabised because it is believed that Ishmael Spoke Aramaic and Egyptian then learnt Arabic from a Qahtanite Yemeni woman that he married. Therefore, the Adnanites are descendants of Abraham. According to Parolin, Modern historiography "unveiled the lack of inner coherence of this genealogical system and demonstrated that it finds insufficient matching evidence".[4]
