Adnan (d. 550 BC) is a legendary figure in Arab tradition, regarded as the progenitor of the northern Arab tribes. His life is primarily known through oral histories and later Islamic genealogical works, with no contemporary historical evidence. He is considered a descendant of Ishmael and an ancestor of the Quraysh tribe, to which the Prophet Muhammad belonged. Adnan symbolizes Arab identity and tribal unity, though his historical existence remains uncertain.
