          The Power of Peace

          the Sassanid and Byzantine empires were
        
        
          dismantled by divine succour during the period of
        
        
          the rightly-guided caliphs. Consequently, the
        
        
          coercive political system ended at the international
        
        
          level, and thus began an age of intellectual freedom.
        
        
          In this connection we find a very authentic tradition
        
        
          recorded in Sahih al-Bukhari. When, after the
        
        
          caliphate of Ali ibn Abi Talib, Abdullah ibn Zubayr
        
        
          and the Umayyads engaged themselves in political
        
        
          confrontation, Abdullah ibn Umar (son of the
        
        
          second Caliph) and the senior-most surviving
        
        
          companion of the Prophet kept himself aloof from
        
        
          this battle. A group of people came to him and,
        
        
          referring to the verse (2:193), which commanded the
        
        
          believers to do battle in order to put an end to
        
        
          persecution, asked him why he was not willing to
        
        
          join the battle, Abdullah ibn Umar replied that
        
        
          ‘fitna’
        
        
          did
        
        
          not refer to their political confrontation,
        
        
          but referred rather to religious persecution, which
        
        
          they had already brought to an end. (
        
        
          Fathul Bari,
        
        
          8/160).
        
        
          This makes it clear that the war putting an end to
        
        
          persecution was a temporary war, of limited
