Unlike many other Muslim countries, Saudi Arabia has been following a strict version of Islam where for example, men and women are segregated in universities. Another example of the strict adherence to Islamic values can be seen in women who are required to wear the traditional abaya (long, fully covered dress). However, women are no longer required to wear abayas in public but are required to dress modestly as a form of respecting the Saudi culture. Additionally, Saudi Arabia is the only Muslim country where shops and other public facilities are required to close during prayer time which takes place five times a day and employees and customers are sent off to pray. Thus, the religious police (also known as Haia or Mutaween), who patrol the streets enjoining good and forbidding wrong by enforcing dress codes, strict separation of men and women, attendance at prayer (salat) five times each day, the ban on alcohol, and other aspects of Sharia (Islamic law) or behavior it believes to be commanded by Islam. Cinema theatres were shut down in 1980, for example. However, Saudi Arabia has reopened cinema theaters since April 2018.
