In Saudi Arabia, the rulers follow the branch of Sunni Islam. People who follow this branch believe in the supremacy of the Quran as the ultimate authority, the teachings of the Prophet Muhammad as the source of guidance, the concept of tawhid (oneness of God), the importance of the Five Pillars of Islam (faith, prayer, charity, fasting, and pilgrimage), and the belief in the finality of prophethood with Muhammad as the last and final prophet.
