Uyayna (Najd)
Al-Uyayna, an oasis settlement in the Najd region of central Saudi Arabia northwest of modern Riyadh, is the birthplace of Muhammad ibn Abd al-Wahhab (d. 1792), the reformer whose teaching gave rise to the Wahhabi movement; it was in Uyayna and then Diriyya that his alliance with the Al Saud began.
