          oath of allegiance (623
        
        
          a
        
        
          .
        
        
          d
        
        
          .), when 75 peopl e of Madinah (73 men
        
        
          and 2 women) came to the Prophet and accepted Islam, they were
        
        
          told by the Prophet to appoint twelve leaders (
        
        
          
            Al-Bidayah wan-
          
        
        
          
            Nihayah
          
        
        
          , Vol. 3, p. 160). So they chose twelve responsible persons
        
        
          from among themselves. Three belonged to theAws tribe and nine
        
        
          to the Khazraj tribe. Then the Prophet addressed them thus:
        
        
          “You are the guardians of the believers of Madinah” (
        
        
          
            Zarqani
          
        
        
          ,
        
        
          Vol. 1, p. 382). The leadership of Jafar, who was appointed leader
        
        
          of the emigrants to Abyssinia was also of this nature (
        
        
          
            Seerat ibn
          
        
        
          
            Hisham
          
        
        
          ). Similarly, whenever Muslims spread out from Arabia
        
        
          across the world, they endeavoured to establish their social
        
        
          structures. In addition to leading an Islamic life and calling others
        
        
          to Islam, they gave basic importance to organization, so that they
        
        
          were able to perform their religious duties under one leader.
        
        
          The last stage of Islamic organization is the formation of a
        
        
          political setup which, in religious terminology, is called
        
        
          
            Nasb-e-
          
        
        
          
            Imamat
          
        
        
          , the appointment of an Imam. According to all schools of
        
        
          religious thought, the establishment of a political and social leader
        
        
          of Muslims is obligatory. This matter is so important that there is
        
        
          not a single book on religious law and creeds which has not dealt
        
        
          with this issue.
        
        
          It is specially stated in
        
        
          
            Sharh al-Mawaqif
          
        
        
          ,
        
        
          
            Sharh Maqasid
          
        
        
          and
        
        
          
            Aqaaide al-Nasafi
          
        
        
          that it is compulsory for Muslims to have an
        
        
          
            Imam
          
        
        
          . With one minor exception, no group disagrees over this
        
        
          issue. Ibn Hazm writes:
        
        
          All Sunnis, Murjea, Shia, and Khawarij (except the now extinct
        
        
          Najdat sect) agree on the obligatory nature of the
        
        
          
            Imamat
          
        
        
          (
        
        
          
            Al Melal
          
        
        
          
            wa al Nehal
          
        
        
          , p. 72).
        
        
          The only difference of opinion on this matter is that the people
        
        
          of the
        
        
          
            Ahl al-Sunnah wa al Jama’a
          
        
        
          take this to be a canonical order,
        
        
          while some other groups, such as
        
        
          
            Zaidiya
          
        
        
          and
        
        
          
            Mutazela
          
        
        
          , consider
        
        
          it necessary as being the demand of reason. But, as mentioned
        
        
          above, the matter of appointing a political leader is relevant only
        
        
          in a Muslim society which has acquired an independent status as a
        
        
          social group and, as such, is in a position to set up its own separate
