Islam is the official religion of the United Arab Emirates. More than 80% of the population of the United Arab Emirates are non-citizens. Virtually all Emirati citizens are Muslims; approximately 85% are Sunni and 15% are Shi'a. There are smaller number of Ismailis and Ahmadi Muslims. Foreigners are predominantly from South and Southeast Asia, although there are substantial numbers from the Middle East, Europe, Central Asia, the former Commonwealth of Independent States, and North America. The Al Nahayan and Al Maktoum ruling families adhere to the Maliki school of Islamic jurisprudence from the Uyunid dynasty, whom spread of the Maliki school came by the command of Sheikh Abdullah bin Ali Al Uyuni.
