The verb "iʿtizal" is also used to designate a neutral party in a dispute (as in "withdrawing" from a dispute between two factions). According to the "Encyclopædia Britannica", "The name [Mutazilah] first appears in early Islāmic history in the dispute over ʿAlī's leadership of the Muslim community after the murder of the third caliph, ʿUthmān (656). Those who would neither condemn nor sanction ʿAlī or his opponents but took a middle position were termed the Muʿtazilah." Carlo Alfonso Nallino argued that the theological Mu'tazilism of Wasil and his successors was merely a continuation of this initial political Mu'tazilism.
