We will not leave advising you...
We will not leave advising you, and that we have to mention what we think that we have a proof against you or that which return you to the unity and the community. Our leader is he whose merits you and the Muslims have known well. And I do not think that this is not clear to you. The men of religion and virtue do not regard you as equal to Ali and do not prefer you to him. Therefore, fear Allah, O Mu’awiya, and do not oppose Ali.
We have never seen a man more pious, ascetic, and of high qualities than him.” Mu’awiya knew Imam Ali’s outstanding merits. However, it was his spites and ambitions that came between him and the truth. So he preferred fighting against him. He answered the people, saying: “You have summoned to obedience and unity. As for the unity to which you have summoned (me), it is the best. And as for the obedience to your leader, we do not believe it.
Your companion killed our Caliph (Uthman), divided our community, and lodged those who revolted against us. Your leader claims that he had not killed him. So we do not refuse that. Have you seen those who killed our leader (Uthman)? Do you not know that they are the companions of your leader? Therefore, he should give them to us to kill them for him (Uthman). And we will respond to you for obedience and unity.” The speech of Mu’awiya was full of lies and fallacies.
He accused Imam Ali of murdering Uthman while he knew well that he was innocent of that. Indeed, the good Muslims had killed him, because he had deviated from the truth and altered Allah’s Book-just as we have previously mentioned. Shibth bin Rib‘i opposed Mu’awiya[^1] , saying: “Does it please you, by Allah, O Mu’awiya, that you catch Ammar bin Yasir and kill him?” Shibth bin Rib‘i gave Ammar bin Yasir as an example to Mu’awiya.
It is worth mentioning that Ammar bin Yasir was the greatest personality who revolted against Uthman. Would he have killed him if he had found him? Mu’awiya said to him: “And what prevents me from doing that? By Allah, if your leader let me catch Sumayya’s son (Ammar), I would not kill him for Uthman; rather I would kill him for Na’il, Uthman’s servant!” And what would have prevented Mu’awiya from killing Ammar if he had found him?
He would have done that for authority and the rebellion against Islam.
