According to the Islamic Revolution Document Center, Nouri "played a prominent role in the victory of Constitutional movement, but upon seeing its deviation he began to oppose Westernized Policy" and "was among the first Muslim scholars who found out colonial conspiracy to replace Islam with secularism in the disguise of constitutionalism and constitution and so endeavored to prevent nationalism from surpassing Islamism as well as to obstruct domination of western licentiousness and immorality in the society under the name of democracy and freedom." (On colonial power, Britain supported the Constitutionalist movement. Another, Iran's large neighbor Russia, opposed it.)
