Alternative Sources for Sermon 173 (1) Al-Harrani, Tuhaf, 130; (2) Abu Ja`far al-'Iskafi, Naqd al-`Uthmaniyyah, see Ibn Abi al-Hadid, II, 171-173.
[^1]: When the people collected in the Saqifah of Banu Sa`idah in connection with the election, even those who were not present there were made to follow the decision taken there, and the principle was adopted that those present at the election had no right to reconsider the matter or to break the allegiance and those not present could do nothing but acquiesce in the agreed decision.
But when the people of Medina swore allegiance at the hands of Amir al-mu'minin, the Governor of Syria (Mu`awiyah) refused to follow suit on the ground that since he was not present on the occasion he was not bound to abide by it, whereupon Amir al-mu'minin gave a reply in this sermon on the basis of these accepted and agreed principles and conditions which had been established among these people and had become incontrovertible namely that: "When the people of Medina and the ansar and the muhajirun have sworn allegiance on my hand, Mu`awiyah had no right to keep aloof from it on the ground that he was not present on the occasions nor were Talhah and az-Zubayr entitled to break the pledge after swearing allegiance." On this occasion, Amir al-mu'minin did not argue on the strength of any saying of the Prophet which would serve as his final say about the caliphate, because the grounds for refusal in his case was in respect of the modus operandi of the principle of election.
Therefore, in keeping with the requirements of the situation a reply based on the agreed principles of the adversary could alone quieten him. Even if he had argued on the strength of the Prophet's command it would have been subjected to various interpretations and the matter would have been prolonged instead of being settled. Again Amir al-mu'minin had seen that soon after the death of the Prophet all his sayings and commands had been set aside.
