Hinduism is the 3rd largest religion in Saudi Arabia, followed by nearly 1.3% of total population residing in the nation.

[1][2] There has been a large migration of Indians to Saudi Arabia, with the number of Hindus also witnessing a growth.

[7] Most Indians in the earlier waves of emigration to Saudi Arabia were Muslim, but after 2001 the share of Indian Hindus has increased, as has the number of Hindus from the Nepali diaspora, and Hinduism is now the fastest growing religion in Saudi Arabia.

[9] Like other non-Muslim religions, Hindus are not permitted to worship publicly in Saudi Arabia.

This is likely the foundation for the stringent position of Saudi authorities when it comes to idol worshiper religious practice.
