With a population of more than forty thousands, Albadai city is located in the center of AlQaseem area (part of Najd province, Saudi Arabia). It's considered the most important agricultural city in the area. Albadai city consists of six small towns (Alshabeebiah, Umtala'h-my home town-, Alobailh, Almanzelah, Alulowat and Alhajnawee) extended along the banks of Wadi Alrumah ( the Rumah vally). Wadi Alrumah is the longest vally in the Arabian Peninsusla starting from Madena (the Prohet Mohammed's -peace be upon him- city) and ending at Shat Alarab in Iraq. This vally and Alnesa vally- which runs from south to the north- determinded the selection of Albadai's location by its former inhibtants who depended largly on the water supply provided by these two vallies. Albadai is well-known by its huge supply of ground water, its rich soil and its agricultural projects.
