Islam is the state religion in Bahrain. Due to an influx of immigrants and guest workers from non-Muslim countries, such as India, the Philippines and Sri Lanka, the overall percentage of Muslims in the country has declined since the late 20th century. Bahrain's 2010 census indicated that 70.2% of the population is Muslim. The last official census (1941) to include sectarian identification reported 16% as Shia and 84 per cent as Sunni of the Muslim population.

Beit Al Qur'an is a multi-purpose complex dedicated to the Islamic arts and is located in Hoora, Bahrain. Established in 1990, the complex is most famous for its Islamic museum, which has been acknowledged as being one of the most renowned Islamic museums in the world.
