"President Assad said that extremist and Wahhabi thought distort the real Islam, which is tolerant," state news agency SANA said.
"He underlined the role of men of religion in fighting against Wahhabi thought, which is foreign to our societies," the agency said.
Wahhabism is an ultra-conservative Muslim tradition, which is predominant in Saudi Arabia and applied to both religious and political life.
