Omani Rial (OMR) = 1,000 baiza. Notes are in denominations of OMR50, 20, 10, 5 and 1, and 500, 250, 200 and 100 baiza. Coins are in denominations of 50, 25, 10 and 5 baiza.
The religion of Oman is Islam, but Oman is a special case being the only country in the world where neither Sunni nor Shi'i dominates, rather the smaller branch of Ibadism.
Even though Oman is a modern country, western influences are quite restricted. The Ibadi form of Islam is also conservative like Sunni Islam and Shi'a Islam. About 75% of Oman is Muslim. As is the case with most Middle Eastern countries, alcohol is only available in some hotels and few restaurants.
