Touching upon that Mu'awiya not only secured the authority that year, but also he held sway over other members of the Shura (council), Muhajiruns and Ansars, Jahi’ has stated, “Mu'awiya named that year as **عام الجماعة “**The year of Community” whereas that year was, عام فُرقةٍ وقهر وجبر وغلبة “The year of separation, wrath, constraint and predominance.” The year therein Imamate turned into monarchism and Kasra system and caliphate became usurped and Caesarean.[^17] Afterwards, the principle of “Sovereignty does belong to the one who suppress others” turned an incontrovertible principle in political Fiqh (religious jurisprudence) of Sunnism.
Since the inception of his revolt against Imam 'Ali (a), Mu'awiya's legal mainstay has been his recourse to his kinship with 'Uthman in addition to his self-introduction as his next of kin. He alleged that the assassin of 'Uthman had been 'Ali (a) and he as his next of kin would retaliate his assassins. And gradually it turned into hereditary transfer of caliphate from 'Uthman to Mu'awiya in the view of Damascus dwellers, for materializing which Mu'awiya himself played a pivotal role.
Prior to this, it should be taken into consideration that Mu'awiya deemed himself the successor of Qurayshi power which had transferred from Abu Bakr and 'Umar to 'Uthman. We earlier referred to Muhammad Ibn Abi Bakr's letter to Mu'awiya therein the former had reproached him for his insistence on inequity about 'Ali (a).
As its response, Mu'awiya wrote, “Your father and I during our prophet's lifetime had held 'Ali's right incontestable and had indeed discerned his supremacy; nevertheless, usurping his right, your father and 'Umar, after prophet's departure, were the ever-first ones who summoned him to swear allegiance to them. He did swear allegiance under duress, they two, yet, granted naught as an allotment to him. After those two, 'Uthman secured the authority.
If it were assumed a blunder, your father had blundered for the first time and we were all his accomplices, yet if it were approved, we emulated your father. If you intend to reproach, you had better reproach your father first.”[^18] From the beginning of his revolt against 'Uthman, Mu'awiya was doing his utmost to exploit him.
Once he requested 'Uthman to proceed to him in Damascus in order to be immune from the dissenters, 'Uthman rejected however.[^19] Later on, when the revolt aggravated, Mu'awiya found no alternative except 'Uthman's assassination.
