Saudi Arabia is an Islamic state where virtually all citizens are Muslim. Among Saudi nationals, approximately 85-90% are Sunni, following the Hanbali school of jurisprudence as interpreted through Wahhabism/Salafism. The Shia minority (10-15%) is concentrated in the Eastern Province and parts of the southwest.
The total population of 36 million includes approximately 13 million foreign workers, among whom there are Christians (mainly Filipino and Indian), Hindus, Buddhists, and others. Public practice of religions other than Islam is prohibited, though private worship is theoretically tolerated. There is no freedom of religion for Saudi citizens — apostasy from Islam can carry the death penalty.
History of Religion
Saudi Arabia is the birthplace of Islam. The Prophet Muhammad was born in Mecca around 570 CE and received the first Quranic revelations in 610 CE. He migrated to Medina in 622 CE (the Hijra), establishing the first Islamic community. By his death in 632 CE, most of the Arabian Peninsula had embraced Islam.
The modern Kingdom of Saudi Arabia was founded in 1932 by Abdulaziz ibn Saud, who allied with the Wahhabi religious movement. Wahhabism, founded by Muhammad ibn Abd al-Wahhab in the 18th century, advocates a puritanical form of Sunni Islam. Saudi Arabia's vast oil wealth has funded the global spread of Wahhabi/Salafi ideology through mosques, schools, and charities worldwide.
Religious Sites & Landmarks
The Masjid al-Haram (Great Mosque) in Mecca surrounds the Kaaba, Islam's holiest site and the direction of prayer for 1.8 billion Muslims worldwide. The mosque can accommodate over 2 million worshippers. The Al-Masjid an-Nabawi (Prophet's Mosque) in Medina is the second-holiest site, containing the tomb of Prophet Muhammad.
The Hajj pilgrimage to Mecca, one of Islam's five pillars, draws over 2 million Muslims annually. The Plain of Arafat, Mount Hira (where Muhammad received the first revelation), and Mina are key Hajj sites. Non-Muslims are prohibited from entering Mecca and Medina. The Mada'in Salih archaeological site in Al-Ula contains pre-Islamic Nabataean tombs.
Religion in Daily Life
Islam governs virtually every aspect of life in Saudi Arabia. The legal system is based on Sharia (Islamic law). Businesses close during the five daily prayer times. The religious police (Mutawwa'in), though their power has been curtailed under recent reforms, historically enforced dress codes, prayer attendance, and gender segregation.
Recent Vision 2030 reforms under Crown Prince Mohammed bin Salman have brought significant social changes: women can drive, cinemas have opened, and entertainment events are now permitted. However, Islam remains the foundation of governance and social life. Ramadan is strictly observed, with eating, drinking, and smoking in public prohibited during daylight hours. Religious education is a major component of the school curriculum.
