Shia view of Umar  Umar ibn al-Khattab was one of the earliest figures in the history of Islam. While Sunnis regard Umar ibn al-Khattab in high esteem and respect his place as one of the "Four Righteously Guided Caliphs", the Shia do not view him as a legitimate leader of the Ummah and believe that Umar and Abu Bakr conspired to usurp power from Ali. Shia believe that the Sunni view of Umar was created by the later Umayyad dynasty to honour the man that gave power to the first Umayyad ruler and third Sunni Caliph, Uthman. In this way, it gives legitimacy to Umar's consultation that started their own dynasty. Shia believe that the Umayyad view was propagated with lethal force and heavy duress and as time went on, that view became predominant and eventually taken as truth, cemented by the works of Bukhari. A Sh'ia scholar states:  Hafsa, the daughter of Umar, was originally married to Khunais ibn Hudhaifa. When he died, Umar sought to find a husband for her. He approached his friend Uthman who said "I am of the opinion that I shall not marry at present", after thinking about the proposal for a few days. Umar became angry with Uthman and asked Abu Bakr the same thing. Abu Bakr did not give him a reply, causing Umar to become even more angry with him than he was with Uthman. Umar then preceded to Muhammad to discuss the previous two incidents. Muhammad reassured Umar by saying that "Hafsa will marry one better than Uthman will marry one better than Abu Bakr." Umar was obviously alluding to the fact that Hafsa was to marry Muhammad and that Uthman was to marry a daughter of Muhammad. Hafsa was married to Muhammad in 625. Muhammad's household was not always peaceful as his wives were in two groups. Umar said on one occasion:   writes:  Shia claim that the despair felt by Umar at the time of Muhammad's death was not genuine, they insist that there was no despair, only threats aimed to delay matters so that his friend and confederate Abu Bakr could return before Ali was confirmed as the successor. As for Ali's allegiance to Abu Bakr's rule, this too was made up to support Abu Bakr's claim to power.   writes:  Shi'a view Umar as the "khalifa-maker" of Abu Bakr and that during Abu Bakr's khilafat, Umar was his principal adviser.
