Wadi Hanifa (Arabic: وَادِي حَنِيْفَة, romanized: Wādī Ḥanīfah), historically known as Wadi al-Arad, is a wadi (seasonal river) in the Najd region, Riyadh Province, in central Saudi Arabia. The valley runs for a length of 120 km (75 mi) from northwest to southeast, cutting through the city of Riyadh, the capital of Saudi Arabia. A string of towns and villages lie along the valley, including Uyaynah, Irqah and Diriyah. The historical city of Riyadh itself is on the northeastern side of the wadi, but the city has now expanded across Wadi Hanifa, with the sub-municipalities of Al-Shifa and Al-Urayja on its southwestern side.

Muhammad bin Saud Al Muqrin Al Saud (Arabic: محمد بن سعود آل مقرن, romanized: Muḥammad bin Suʿūd Āl Muqrin; 1687–1765), also known as Ibn Saud, was the emir of Diriyah and is considered the founder of the First Saudi State and the Saud dynasty, named after his father, Saud bin Muhammad Al Muqrin. His reign lasted between 1727 and 1765.

Musaylima (Full name: Muslima ibn Habib al-Hanafi) (Arabic: مُسَيْلِمَةُ), d.632, was a claimant of prophethood from the Banu Hanifa tribe. Based from Diriyah in present day Riyadh, Saudi Arabia, he claimed to be a prophet and was an enemy of Islam in 7th-century Arabia. He was a leader of the enemies of Islam during the Ridda wars. He is considered by Muslims to be a false prophet (نبي كاذب). He is commonly called Musaylima al-Kadhāb (مسيلمة الكذاب, 'Musaylima the Arch-Liar') by Muslims. Musaylima was said to have composed in saj', a type of rhymed prose that was common in pre-Islamic artistic speech.

The Banu Ghani (Arabic: بنو غني) was an Arab tribe that inhabited the area between Bisha and Diriyah in pre-Islamic Arabia and parts of which migrated to Syria during the Muslim conquest of that region.
