The United Arab Emirates has a diverse multicultural society influenced by Islamic and Arab culture. Islam is the official religion, and there are mosques scattered around the country that call Muslims to prayer five times daily. The UAE is a federation of seven emirates governed as absolute monarchies, with the ruler of Abu Dhabi serving as president and the ruler of Dubai as prime minister. While Islam is the largest religion, Christianity and other faiths are also practiced by non-nationals living in the UAE. The country has a hot, dry climate, and Abu Dhabi serves as the capital city.
