8. These Early Terrorists Saw the Most Minor of Sins as Apostasy Punishable by Death
In their struggle against the first Umayyad Caliph, Muawiya I, the Khawarij contended that he was illegitimate because he gained the Caliphate by force of arms, rather than election by the Muslim community. In the protracted fight that ensued, the Khawarij earned an evil reputation among contemporary Muslims as horrific radicals. On the one hand, they adopted and stuck to democratic and egalitarian principles, whereby governance was to be entrusted to Caliphs elected by and responsible to the Muslim community.
Commendable as those principles might have been, they were more than counterbalanced by a fierce fanaticism that horrified and turned off many. They contended that Muslims who backslid or sinned, such as those who drank alcohol, fornicated, missed the daily prayers, failed to fast on Ramadan, or even engaged in idle gossip, had engaged in behavior that rendered them apostates, and thus worthy of the death penalty. The Khawarij launched a program of terror against the Caliph’s supporters, as well as those who failed to meet their purity standards.
