Be kind enough to go to the Caliph and persuade him in suitable words to leave Ammar alone and not to banish him from the city otherwise such a disturbance will stir as would hardly be quelled". Imam Ali listened to them, consoled them and asked them not to make haste. He told them, "I'll go to the Caliph and will try to settle the matter. I am sure it will be settled amicably. I am fully conscious of the situation. I'll bring him round to your view point.
After this Ali went to Caliph Uthman and said, "O Uthman! You are too hasty in some matters and ignore the suggestions of friends and advisors. Once you turned Abu Dharr out of Medina. He was a very virtuous Muslim, a dignified companion of the Prophet of Allah and the best of immigrants. You sent him to Rabzah where the poor fellow died in solitude. On account of this incident, the Muslims have turned all the more against you.
Now I hear that you have decided to banish Ammar as well from the city. This is not a good thing. Have fear of Allah and desist from banishing Ammar from Medina. For Allah's sake don't give such troubles to the companions of the Prophet and let them live in peace". Hearing this Uthman angrily said to Ali. "You should be the first to be banished from the city because it is you who are ruining Ammar and others". Hearing these indecent words Ali said, "O Uthman!
How dare you think like this about me? You will not be able to do it even if you wish it, and if you doubt my words just try. Then you will realize the actual state of affairs and will come to know whom you are facing. And now you say that I am ruining Ammar and others. By Allah all this disorder is from your side. I don't see any fault with them. You are committing such acts as are against the religion and decency.
People cannot tolerate them, and are turning against you, and you cannot tolerate these things. You fell offended with everyone and then you cause them trouble. This attitude is far from the ways of the elders". After that he rose from there and went out. When the people of Bani Makkzum came to Ali, to know what the Caliph had told him in their case, Ali said, "Tell Ammar to remain indoors and not to come out. Allah will save him from the evil designs.
The Caliph also came to know of this conversation through somebody and he gave up the idea of exiling Ammar.
