Saudi Arabia’s top religious official has blamed Muslim sinfulness for instability in the Middle East, where pro-democracy unrest has toppled four heads of state.

“The schism, instability, the malfunctioning of security and the breakdown of unity that Islamic countries are facing these days is a result of the sins of the public and their transgressions,” Grand Mufti Sheikh Abdulaziz Al al-Sheikh was quoted as saying by al-Watan newspaper.

In a Friday sermon, he accused “chaotic” people of wearing mask of “democracy and equality” for actions leading to injustice and instability within the umma, or Muslim nation.

Revolts that erupted last year have removed Arab autocrats in Tunisia, Egypt, Libya and Yemen and are still raging in Syria and Bahrain. They gave voice to millions of people who suffered decades of repression but have alarmed Gulf Arab rulers.
