Uthman was succeeded as Caliph by Ali, and Ali was assassinated merely five years after his assumption of office as Caliph. If Uthman had not been assassinated there would have been no occasion for the battle of the Camel or the battle of Siffin. There could likewise be no occasion for the revolt of the Kharijis. And if there had been no revolt of the Kharijis, there would have been no assassination of Ali. Over ten thousand persons were killed in the battle of the Camel. There was a large scale massacre of the Kharijis at the battle of Nahrawan. The battle of Siffin also claimed a heavy toll. In these battles something like twenty to thirty thousand Muslims were killed All this valuable loss of Muslim life would not have occurred, if Uthman had not been assassinated. Thus those w, ho assassinated Uthman were not merely guilty of the murder of one old man; they were guilty of the massacre of the Muslims at large.
