fort Muhanna bin Sultan was a younger brother of the great Imam
Saif bin Sultan (r. 1692–1711). He was the great-uncle of
Saif bin Sultan II, the eldest son of
Sultan bin Saif II (r. 1611–1718). Saif bin Sultan II was aged twelve when his father died in 1718. In theory the office of Imam was elected, but in practice for many years it had been inherited by members of the Ya'Aruba family. Saif bin Sultan II was therefore seen as the natural successor to his father. However, there was support for appointing Muhenna as regent during Saif's minority. An assembly of Sheikhs and other notable people was convened at
Rustaq, where the Kadhi Adey bin Suliman was persuaded to proclaim Saif bin Sultan II the Imam, albeit reluctantly. Although Saif was popular among the people, the
ulama considered he was too young to hold office and favored Muhanna as Imam. Muhanna was well-qualified since he was learned, wise and careful in his decisions. ==Reign==
