More recently, Abd al-Aziz ibn Baz (Wahhabi scholar and Grand Mufti of the Kingdom of Saudi Arabia at the time), responded to an article which included some ideas against the concept of abrogation, by stating that the author was guilty of "an act of clear disbelief, a repudiation of Islam, and denial of Allah the Glorious and His Prophet on whom be peace ... It is obligatory upon the governing authority to have that man brought to the courts and ask that he retract his statements, and to rule upon him according to that which the pure Shari'ah summons". (Ibn Baz having called for the execution of Muslims guilty of what he considered acts of unbelief on other occasions.)
