Strategy of Muawiyah
After the conquest of Egypt, the strategy of Muawiyah was that discontent should be created in the territories under the control of Ali. A vigorous propaganda campaign was whipped up accusing Ali of breach of faith in not accepting the verdict of the umpires at Dumatul Jandal, whereas according to the pact executed at Siffin such verdict was to be binding. In these territories there were already many tribes which were pro-Othman. Those tribes were bribed to carry on propaganda against Ali, and sponsor activities likely to subvert the administration of Ali in the various provinces.

"The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him."
