Similar to that is the story of (the document of renunciation (bara'a) which the Prophet, may God bless him and his family, gave to Abu Bakr so that he could abrogate the alliance with the polytheists through it. When he had travelled far away, Gabriel, peace be on him, descended to the Prophet, may God bless him and his family. He told him: "God recites His greeting to you and says to you that the act of renunciation should not be performed for you except by yourself or a man (related) to you."
The Apostle of God, may God bless him and his family, summoned 'Ali, peace be on him, and told him: "Ride my camel, al-'Adba', and go after Abu Bakr. Take (the document of) renunciation from him and go with it to Mecca. You abrogate the alliance with the polytheists through it. Give Abu Bakr the choice of continuing to ride with you or of returning to me."
The Commander of the faithful, peace be on him, rode al-'Adba; the camel of the Apostle of God, may God bless him and his family and caught up with Abu Bakr. The latter was disturbed at being caught up with by him.
"Why have you come, Abu al-Hasan?" he asked as he greeted him. "Are you going to travel with me? Or is it for some other reason?"
"The Apostle of God, may God bless him and his family, ordered me to come after you," the Commander of the faithful, peace be on him, said, "to take the verses of renunciation (bara'a) from you and to abrogate the treaty with the polytheists through them. He ordered me to let -you choose between going with me or returning to him."
"Indeed, I will return to him," he said.
He went back to the Prophet, may God bless him and his family. When he came to him, he said: "Apostle of God, you regarded me as worthy to undertake a mission on account of which men craned their necks towards me. When I had set out on it, you dismissed me from it. What has come down in revealed message (Qur'an) concerning me?"
"The trusty one, Gabriel, peace be on him, came down to me from God, the Mighty and Exalted," the Prophet, may God bless him and his family, answered, "with (the command) that: 'The act of renunciation should not be performed for you except by yourself or a man (related) to you.' 'Ali is related to me and it should only be performed for me by 'Ali."
(This account occurs) in a famous tradition. The abrogation of a treaty was limited to the one who made it or to one who could take his place in terms of the necessary obedience, dignified regard, high rank, noble position, and one who was above suspicion in his actions and whose words could not be (legitimately) opposed- one who was the same as the maker of the treaty and whose affair was his affair. Since it was judged by what he had done in the past it was established and was secure from opposition and (since) the strength of Islam, the completion (of the laws) of religion, the well-being of the Muslims, the conquest of Mecca, and the good organization of well-being was involved in the abrogation of the treaty, God, the Exalted, preferred that that should be entrusted to one who was illustrious in name, exalted in fame. This indicates the outstanding merit of such d man; it gives evidence of his high rank and distinguishes him from others. Those (things) belonged to the Commander of the faithful, peace be on him. None of the other people had merit which came near to the merit which we have described nor did any of them share with him (any) of what we have explained.
Examples of what we have mentioned are so numerous that our work in presenting them would lengthen this book, and the speeches would encompass it. It is sufficient for those of intelligence to include what we have set out in the aims which we have outlined.
