Saudi Arabia is the birthplace of the Islamic faith. Additionally, all faiths other than Sunni Islam are illegal in Saudi Arabia.
The Saudies are mostly the Sunni Muslims following the jurisprudence of Imam Ahmad Bin Humbal (RA). Of the various divisions of Hanbali Sunni Muslims, the King of Saudi Arabia is considered a Wahhabi Muslim.
The dominant form of Islam in Saudi Arabia is Wahabi. This is a much stricter and more conservative version of Islam, and some of its customs (not allowing women to drive, for example) are at odds with other denominations of Islam.
Sunni Islam is the only legal religion in Saudi Arabia (save for the expatriate cities where American engineers live). There are Hindus, Christians, and Shiite Muslims who live in Saudi Arabia, but their practices and religions are not protected and often violated by the Saudi government. Judaism is expressly forbidden.
