The Omani culture has its roots firmly in the Islamic religion. Oman developed its own particular form of Islam, called Ibadhism, after its founder, Abdullah ibn Ibadh who lived during the 7th century AD. Not all Omanis are Ibadhis, however: there are also Sunni Muslims and Shia Muslims. Omanis are not only tolerant of the beliefs of different Muslim divisions, they are also tolerant towards believers of other faiths, who are allowed to practise their religion in churches and temples.
