Saud bin Muhammad Al Muqrin (Arabic: سعود بن محمد آل مقرن Suʿūd ibn Muḥammad Āl Muqrin; 1640–1726) was the eponymous ancestor of the House of Saud, otherwise known as the al-Saud.
[3] The Mrudah are believed to be descended from the Banu Hanifa branch of the Rabi'ah tribal confederation.
[3] The Al Saud originated as a leading family in a town called Diriyah, close to the modern city of Riyadh, near the center of Najd.
Sometime in the early 16th century, ancestors of Saud bin Muhammad took over some date groves, one of the few forms of agriculture the area could support, and settled there.
[8] Two decades after Saud's death, his son Muhammad bin Saud made his historic pact with Muhammad bin Abd al-Wahhab, leading to their conquest of Arabia and the establishments of the First Saudi State.
