Muhammad bin Saud and Imam Muhammad bin Abdul Wahhab found they had interests in common, pre-eminently a desire to see all the Arabs of the Peninsula brought back to Islam in its simplest and purest form. In 1744, they therefore took an oath that they would work together to achieve this end. Muhammad bin Saud's son, Abdul Aziz, married the daughter of Imam Muhammad. Thus, with an oath and a marriage, the two leaders sealed a pact between their families which has lasted through the centuries to the present day.
