28. Radicalization of the Khawarij
Muslims elected the first three Caliphs, or successors of the Prophet, from outside Muhammad’s family, bypassing his cousin and son-in-law Ali each time. On the fourth try, following the murder of the third Caliph, Ali was finally elected. However, the third Caliph’s relatives, the Umayyads, accused Ali of being implicated in the murder, and elected another Caliph. The rival Caliphs went to war, but before the issue was settled in battle, Ali was prevailed upon to accept arbitration.
The Khawarij, who until then had supported Ali, opposed arbitration. Viewing the Caliphate as the collective property of the Muslim community, they argued that Ali had no authority to make a decision regarding who gets to be Caliph. Election by the community was the sole legitimate process for bestowing the Caliphate, argued the Khawarij, and the Muslim community had already elected Ali. By accepting arbitration to decide who would be Caliph, Ali was overstepping his boundaries and usurping a power of decision that was not his.
