Islam in Bahrain

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. Although the country is majority-Shiite, the al-Khalifa monarchy is Sunni.

Prior to Islam, the inhabitants of Qatar and Bahrain practiced Arabian paganism, worshipping idols. Islam swept the entire Arabian region in the 7th century. Muhammad sent his first envoy Al-Ala'a Al-Hadrami to Munzir ibn Sawa Al Tamimi, the ruler of the historical region of Bahrain, which extended the coast from Kuwait to the south of Qatar including Al-Hasa, Qatif, and the Bahrain Islands, in the year 628 AD, inviting him to Islam. Munzir announced his conversion to Islam and all the Arab inhabitants of Bahrain and Qatar including some Persians living in Qatar also became Muslim, heralding the beginning of the Islamic era in Bahrain.

The Ismaili Shia sect known at the Qarmatians seized Bahrain in 899 CE, making it their stronghold and base of operations. They raided Baghdad and in 930 sacked Mecca and Medina, desecrating the Zamzam Well with the bodies of Hajj pilgrim and taking the Black Stone with them back to Bahrain where it remained for twenty years. The Qarmatians were eventually defeated by their Ismaili counterparts, the Abbasids in 976 and afterwards their power waned.
