'Uyayna

Al-'Uyayna or Al-'Uyaynah (Arabic: العيينة‎‎) is a village in central Saudi Arabia, located some 30 km northwest of the Saudi capital Riyadh. Al-Uyaynah was the birthplace of Muhammad ibn Abd al-Wahhab, whose followers are known as the Wahabis. Today, Uyaynah is a small village and forms together with its neighbor al-Jubayla the Subgovernorate of Al-Uyaynah and Al-Jubayla, with a combined population of 4,000. The subgovernorate is part of the Governorate of Dir'iyyah, which in turn is part of Riyadh Province.

Al-Uyaynah is located inside the narrow, dry river-bed of Wadi Hanifa, which continues southwards through Dir'iyyah and Riyadh. The area where Uyaynah is located was the homeland of Musaylima, who claimed to be a prophet following Muhammad's death in 632, and led his tribe, the Banu Hanifa, against the Muslim conquest of the area. The Battle of Yamama between Musaylima and the Muslim general Khalid ibn al-Walid occurred nearby, and a graveyard for the fallen Muslim warriors from that battle is located adjacent to the village.

The name Uyaynah, which is the diminutive word for "water spring", was not used for the settlements in the area in that period. Instead, early Muslim geographic sources, such as Yaqut, mention the towns of 'Aqraba, Budha, and al-Haddar, the latter said to be Musaylima's home village. Geographic sources do, however, mention, a spring in the area by the name of "al-Uyaynh", from which the name "al-Uyaynah" probably derives.
