Buraidah in the context of "Wadi al-Rummah"

Najd is a historical region of the Arabian Peninsula that includes most of the central region of Saudi Arabia. It is roughly bounded by the Hejaz region to the west, the Nafud desert in al-Jawf to the north, ad-Dahna Desert in al-Ahsa to the east, and Rub' al-Khali to the south, although its exact boundaries cannot be determined due to varying geographical and political limits throughout history.

Administratively, Najd is divided into three main regions: the Riyadh region which features Wadi Hanifa and the Tuwaiq escarpment, which houses easterly Yamama with the Saudi capital, Riyadh since 1824, and the Sudairi region, which has its capital in Majmaah. The second region, Al-Qassim, houses the fertile oases and date palm orchards spread out in the region's highlands along Wadi Rummah in central Najd with its capital in Buraidah, the second largest Najdi city, with the region historically contested by the House of Rashid to its north and the House of Saud to its east and south. The third administrative unit is northerly Ḥa'il, which features the mountains of Jabal Shammar housing the Tayy capital of Ḥa'il.

Az Zulfi (also Zulfi, Zulfy City or Al Zulfi or Az Zilfi) is a city in Riyadh Province in central Saudi Arabia, about 260 kilometres northwest of Riyadh. It is connected by Roads 418 and 535 which both link with the main Highway 65 which connects Riyadh to Buraidah which is about 101 kilometres by road to the west of Al Zulfi. Zulfi also forms a governorate of Riyadh Province. The Al-Yamama/Tuwaiq mountain range begins in the desert to the north of Al Zulfi.
