The Saudi cleric Sheikh Abdel-Rahman al-Barrak, regarded by many as the highest authority for Wahhabi Muslims, doesn't like Shi'ites. In a fatwa issued this week he said: "The rejectionists (Shi'ites) in their entirety are the worst of the Islamic nation's sects. They bear all the characteristics of infidels. They are in truth polytheist infidels, though they hide this."
"The Sunni and Shi'ites schools of Islam are opposites that can never agree, there can be no coming together unless Sunnis give up their principles," the fatwa said.
Barrak was among 38 clerics who issued a statement this month calling on world Sunnis to support their brethren in Iraq.
Meanwhile in Iraq the Su-Shi war of words and swords is escalating. An Iraqi militant group linked to al Qaeda urged Iraq's Sunni Muslims to wage war on the country's Shi'ite Muslims.
"Stand like one man ... and cut their (Shi'ites') throats, spill their blood, burn the ground underneath them, and rain bombs on them," said the speaker, who said he was the official spokesman of "the Islamic state in Iraq".
"They (Shi'ites) have done more than the crusaders (U.S.-led forces) have been doing. They killed men, rendering women widows and children orphans, burned houses of God and tore his book."
