Ibn Abdelwahhab sought refuge in the settlement of Dir’iya, ruled by Muhammad ibn Saud, founder of the dynasty, and suggested they combine forces. Under the banner of religion and war against anyone who did not abide by Ibn Abdelwahhab’s version of Islam, the two men could expand both territory and wealth. Preaching and military raids would go hand in hand, bringing in land, loot, and zakat, the mandatory alms. The marriage of convenience led to intermarriage between the two families, starting with Ibn Abdelwahhab’s daughter and Ibn Saud’s son.
