He called together the principal Muslims and addressed them thus: "You all know that I have lived among you, and you are aware also of my ties of kindred with you. Yazid is your brother and your nephew. It is my wish that you take the oath of allegiance to Yazid as the next Caliph; then it will be you who will bestow offices and depose from them, who will collect and apportion money".
He was answered by Abdullah ibn Al Zubair, who gave him a choice of three things to do, first he might do as Allah's Messenger had done and appoint no successor, second he might do as Abu Bakr had done and nominate a successor, third he might do as Umar had done, and hand over the whole matter to a council of six individuals, none of whom was a member of his own immediate family. Mu'awiya's anger was kindled, and he asked "Have you any more to say?" "No".
Mu'awiya turned to the remainder of the company "And you?" "We agree with what Ibn Al Zubair has said", they replied. Then he addressed the meeting in threatening terms: "The one who warns is blameless. I was speaking among you, and one of you was bold to get up and call me a liar to my face. That I will bear and even forgive.
But I stand to my words, and I swear by Allah that if any of you speaks one word against the position that I take up, no word of answer will he receive, but first the sword will take his head. And no man can do more than save his life".
Thereupon the commander of Mu'awiya's guard ordered two men to stand over each of the nobles of the Hejaz who opposed him and to each he said, "If your man leaves his guards to speak one word, either for me or against me, then let the guards strike off his head with their swords". Then he mounted the pulpit and proclaimed: "These men are the Leaders and the choicest of the Muslims; no matter can be successfully handled without them, nor can any decision be taken without their counsel.
They are now satisfied to take the oath to Yazid , and have indeed already taken that oath by the name of Allah". So the people took the oath. Mu'awiya bribed people to give bayya to Yazeed We read in al Kamil Volume 3 page 350: "Mu'awiya kept Mugheera in his post. Mugheera arrived at Kufa and spoke to his close representatives, bribing them with 30,000 dirhams to maintain their support.
Mugheera sent his son Musa bin Mugheera to Head a delegation that visited Damascus, there they [the group] reiterated their support for the nomination of Yazeed as Khalifa.
