A green field with the Shahada — the Islamic declaration of faith — in white Thuluth script, above a white horizontal sword pointing toward the hoist. Green is the traditional colour of Islam. The Shahada is the central tenet of Islamic faith: 'There is no god but Allah; Muhammad is the messenger of Allah.' The sword represents the strict justice with which the founder unified the kingdom. Saudi Arabia's flag is one of only a few in the world that displays text. It is never flown at half-mast out of respect for the Shahada. Practise the Saudi Arabia flag in the Flagzio Asia flag quiz across all eight game modes.
