A brief introduction of each of the “triumvirs” is given hereunder to enable the reader to understand the concatenation of the events that led to the second civil war in Islam. Talha bin Obaidullah Talha's father, Obaidullah and Abu Bakr's father, Abu Qahafa, were brothers. Talha's mother was the daughter of Hadhrami, and his father, Obaidullah, was her second husband. For a short time, she had also been the wife of Abu Sufyan, the father of Muawiya but he had divorced her.
Talha was married to Umm Kulthoom, the daughter of Abu Bakr, and this made him Ayesha's brother-in-law. When Abu Bakr appointed Umar his successor, Talha strongly protested, and drew his attention to the highhandedness of the khalifa-designate. Later, when Umar himself was dying, he had made Talha a member of his electoral committee. Talha broke his pledge of loyalty to Ali because the latter did not make him the governor of Basra.
He had, probably, the same reason for his opposition, earlier, to Uthman, who also had not appointed him a governor. Baladhuri, the Arab historian, says in his book, Ansab-ul-Ashraf, vol. I, p. 113: “Among the companions of the Messenger of God, there were few who castigated Uthman so viciously as Talha did.” When Uthman's palace was besieged by the rebels, it was Talha who did not let his (Uthman's) slaves bring water in it. At night, he shot arrows at the palace but Uthman knew about it.
Tabari, the historian, says in his History, vol. III, p. 411: “Uthman often prayed:’O God! Save me from the harm that Talha might do to me. He is the one who has inflamed the people against me, and he is the one who has caused my house to be besieged.” Talha's hatred of Uthman must have been colossal. He could not condone his aberrations even after his death. He ordered Uthman's bier and his pall-bearers to be stoned.
Uthman could not even be buried in the cemetery of the Muslims; he had to be buried in the cemetery of the Jews. Zubayr bin Awwam Zubayr's mother was Safiya, the daughter of Abdul Muttalib bin Hashim. Thus his mother was the paternal aunt of Muhammad and Ali. Zubayr also was married to one of the daughters of Abu Bakr, and this made him a brother-in-law of Ayesha. Like Talha, he too protested to his father-in-law against the appointment of Umar as khalifa.
And when Umar was dying, he made Zubayr also a member of his electoral committee. Ibn Saad says in his Tabqaat that Zubayr was also incredibly rich like Talha.
