He bought and sold keys, locks and haberdashery items, hawking the items in public places, particularly in the busy areas adjacent to the markets and mosques.

The older Al Rajhi developed the systems and methods by which they recorded, traded and handled the money they received. Toward the 1950s, Al Rajhi sent his brother Sulaiman to Mecca to conduct the exchange business for pilgrims and business people who had frequented the area. Sulaiman, with the blessing of his older brother remained in Mecca and further expanded to Jeddah which was growing economically at the time as well. The brothers conducted their currency business between the three branches for the next 25 years, which marked the beginnings of Al-Rajhi Bank. Al Rajhi Bank
