• And when he burnt the copies of the Quran which had been gathered from the different parts of the empire When he circulated the official version prepared by Zayd Ibn Thabit . (this has been known as the 'Uthmanic' version ever since ), he was condemned for destroying the word of Allah, through he may have intended to ensure that only the correct version should be read. He was also thought, by some muslims, to be surrounded by people who gave bad advice and took advantage of his age and weakness. 
• Disquiet about Hazrat 'Uthman,s policies and his ability to rule, erupted after six years of his caliphate .Frist there was an uprising in Iraq , then in kufa , and then in Egypt . finally , in 35AH/656AD, troops froms all thtree provinces advanced on Madina to take their complaints directly to the caliph . the force from egypt arrived frist and angrily besiged Hazrat Uthman in his house , but when he agreed to their demands they were pacified . They began their journey home, but hearing he had tricked them , they turned back and began a second siege.
• This siege lasted some time,during which some leading Muslims tried to help Hazrat 'Uthman but were prevented, and eventually some of the Egyptian force, led by Hazrat Abu Bakr's son Muhammad, entered the house and murdered the caliph. It is said that they came upon him while he was reading the Qur'an, and that his blood was shed on it's pages,and also that his wife Na'ila was injured in the affray, while trying to protect him. The Caliph's body was buried by his family in secrecy.
• Hazrat 'Uthman's nephew Mu'awiya had sent troops from Syria to support him,though they arrived too late to save his life. But the governor did not rest until he had hunted down all the assassins of his uncle that he could find, and he demanded that all those responsible for this atrocity should be dealt with as they deserved.Hazrat 'Uthman's murder was to have terrible consequences throughout the community of Islam.   

"Hazrat Usman"

• Hazrat 'Uthman succeeded to the caliphate 23AH/644AD chosen by the council (shura)set up by Hazrat 'Umar as he was dying .He adopted a shorter title than his predecessors,Khalifat Allah,though he continued many of Hazrat 'Umar's policies,including the expansion of Islamic rule.Persia,Armenia,North Africa and parts of the eastern Mediterranean were all brought under the growing empire during his twelve years in the caliphate.
• Hazrat uthman placed closed relatives as governers over many of the new provinces. His nephews, muawiya ibn abi sufiyan had already been appointed governor of syria by hazrat umar, but now he was granted control over more territory. other relatives of the caliph were appointed governors of basra and kufa in southern iraq, and of egypt, and he also made his relatives his close advicers . His reasons for doing this may well have been to ensure loyalty towards himself and to secure the unity of the empire. But to many muslims, this action appeared to be favouring his own family unfairly.
• During the course of hazrat uthman caliphate , criticisms of his actions grew steadily stronger . When he decided to allocate to his governors the wealthy amassed in the compaigns ,rather than divided it between the fighting men themselves,he was accused of favoring his own family, though he may well have been trying to place funds for state purposes with the officials best able to administrate them.
