A Saudi propagandist (writing in the formerly progressive Guardian) on why Saudi Kingdom is a purer form of a Salafite Jihadi Obscurantist Wahhabi regime: "Isis’s adherence to the Kharijite ideology is not the only reason it is not a true Salafi movement; it has also committed an act of disobedience that effectively nullifies its Salafi pretenses. In original Islamic scriptures and practice, the highest authority is the “guardian” of the ummah, (wali al amr). All religious, political and military powers are concentrated under this authority, which Saudi Arabia’s system best exemplifies in the modern world. In other words, King Salman’s legitimacy to rule is contingent on him being first and foremost the wali al amr of the people, and in return the people show their acceptance of his rule by proclaiming him as their ruler. This proclamation (bay’ah) is a contract between the ruler and the ruled in which the first swears to promote Islam and the welfare of the second, and the second swears to obey (ta’ah) the tenets of Islam and follow the first’s leadership. Should the first deviate from Islam, the second is obliged to replace him. The joint bay’ah of the ummah to the ruler is fundamental to Salafism and anyone that breaks the bay’ah – as Isis has done – can never again be considered a true Salafi." (thanks Michael)
