Saudi Arabia Flag:
The flag of Saudi Arabia was officially adopted in 1973.
Saudi Arabia's flag uses green to honor the country's puritanical Muslim Wahabi sect, and also because green is widely believed to be the prophet Muhammad's favorite color.
The white, centered script, the shahada, is the Muslim Statement of Faith: "There is no God but God, and Muhammad is the Messenger of God".
The sword represents Abd-al-Aziz.
Saudi Arabia Coat of Arms:
Adopted in 1950, the emblem of Saudi Arabia is composed of two swords (representing the kingdoms of Hijaz and Nejd) below a palm tree.
