It's true that the constitution doesn't say it, however, Wahhabism is reflected in many of the laws and traditions in the area... Wahhabism is what made all restaurants close during the day in the Holy month of Ramadan, the liquor store and bars too... woman's outfit, her political participation and driving cars just to name a few... unlike other Arabic states from outside the Gulf states and Arabian peninsula who happen to declare themselves "part or the Arab Islamic nation... Ummah" too.
