Saudi Arabia is a fully sovereign Islamic Arab State. The national religion is Islam, and the Book of God and the Sunna of His Messenger (Peace be upon him!) form the cornerstone for the system of government. It has a monarchy, which descends through the male heirs of the founding King of Saudi Arabia, Abdulaziz bin Abdurrahman al-Faisal Al Saud. The line of succession is determined in the light of the worthiness of each heir to rule in accordance with the Book of God and the Sunna of His Prophet (Peace be upon him!).
The system of government is based on the principles of justice, consultation and equality, in accordance with the sharia and national legislative instruments such as the Basic Law of Governance, the Statutes of the Shura (Consultative) Council, the Rules of Procedure of the Council of Ministers and the Provinces Act.
