Mu`awiya said one day to `Amr b. al-`As: O Aba `Abdillah! Which of us is worse? `Amr said: I am [worse] in [my] impulsiveness, and you are [worse] in [your] scheming. Mu`awiya said: You have put me over yourself when I am worse than you in impulsiveness. `Amr said: Where was your slyness on the day you raised the codices (al-masahif)? He said: With this you have overcome me, O Aba `Abdillah. Shall I not ask you about something regarding which you will agree with me? He said: By Allah, lying would be repugnant, so ask what you wish me to agree with. So, he said: Did you cheat me when you advised me? He said: No. He said: Rather, by Allah, you did cheat me – I am not saying in all instances, but in one particular instance. He said: In what instance was this? He said: The day `Ali b. Abi Talib challenged me to a duel, and I sought your advice; I said: “What do you think, O Aba `Abdillah?” So, you said: “It would be honourable.” So, you advised me to duel him whilst you knew who he was; so, then I knew that you had cheated me. He said: O commander of the faithful! A man challenged you to duel him with great honour and great danger. Had you dueled him you would have achieved any of two good outcomes. Either you would have killed him, which would have been the killing of the ages, by which you would have increased in honour and have been free to rule, or you would have accompanied the martyrs and the righteous, which would have been the best of company. Mu`awiya said: This [second outcome] is worse than the first. By Allah, I surely know that, had I killed him, I would have gone to the Fire; and had he killed me, I would have gone to the Fire. `Amr said to him: So, what caused you to go and fight against him? He said: Rulership has no blood bonds; and no one will hear this from me after you.
