Zayd bin Thabit said to Uthman...
Zayd bin Thabit said to Uthman, "If the Caliph wishes we can go to Ali to have an exchange of views with him so that the misunderstandings which have cropped up may be removed and the normal relations are restored". The Caliph said, "You are at liberty to do so". Zayd bin Thabit and Mughyrah bin Ahnas Thaqafi came to Ali, saluted him and took their seats.
Then Zayd bin Thabit started praising Ali and said, “Nobody in the world holds that nearness, kinship, status, and honour with the Holy Prophet which you have. None could equal you in the support of and priority in Islam. You are the fountain of virtue and source of generosity”. After this eulogy Zayd bin Thabit expressed his real aim and said, "O Ali bin Abi Talib! We had gone to Caliph Uthman.
He has made a sort of complaint against you, and has said that you sometimes object to his actions and interfere in matters which he wants to dispose of. So we considered it wise to come to you and explain those things, so that the mutual annoyances and displeasures may be removed, as it will be a matter of joy and pleasure for all the Muslims". Ali said, "By Allah, so long as I could. I never objected to nor interfered with anything.
But, now, matters have come to such a pass that it is not possible to show tolerance or assume silence. I had told him the truth about Ammar which implied his (Uthman's) welfare, safety and expediency. It was my duty which I performed and now it is upto him to do as he pleases". Hearing this Mughyrah bin Ahnas spoke out. "O Ali! You should agree to what the Caliph says or does, whether you are convinced of it at heart or not.
You should consider the obedience to his orders imperative, because he has control over you and you do not have control over him. He has sent us to you only to testify what you say after which he may be considered excused for whatever he says about you". "Having heard Mughyrah's words Ali got angry and said, "By Allah he whom you support will never be honoured and he whom you set in motion, will never be at rest. Be off from me".
Mughyrah was dumbfounded at what Ali said, and he could not utter a word any more. Seeing this Zayd bin Thabit said, "O Ali! Mughyrah talks nonsense. He has said these things of his own accord. By Allah, we have not come to you to bear witness, nor is it our intention to criticize you or to object to what you say. We wanted to open the door of mutual good will and reconciliation and that was the reason for our coming here.
