Although Islam is Oman's state religion, the Basic Law guarantees the “freedom to practice religious rites in accordance with recognized customs...provided that it does not disrupt public order or conflict with accepted standards of behavior.” Freedom House declared in 2005 that “Oman is, overall, a religiously tolerant society,” noting that while non-Muslims “are able to practice their religious rites freely, they are required to register with the government and may not proselytize or publish religious materials.” The U.S. State Department's International Religious Freedom Report for 2011 notes that non-Muslim communities in Oman “are allowed to practice their beliefs without interference only on land specifically donated by the sultan for the purpose of collective worship.” While “gatherings of a religious nature are not allowed in private homes or in any location other than government-approved houses of worship,” Oman's government “has not actively enforced the prohibition.”
