High Quality Content by WIKIPEDIA articles! The Kingdom of Saudi Arabia is an Islamic theocratic monarchy in which Islam is the official religion. Although no law requires citizens or passport holders to be Muslim, almost all citizens are Muslims. Children born to Muslim fathers are by law deemed Muslim, and conversion from Islam to another religion is considered apostasy and punishable by death. Blasphemy against Sunni Islam is also punishable by death, but the more common penalty is a long prison sentence. There have been no confirmed reports of executions for either apostasy or blasphemy in recent years.
