According to the secular historiographic thought, history is primarily a matter of narration, and the task of a historian is to narrate facts as they are. According to thE Islamic historiographic thought, the task of a historian is no merely to narrate facts, but to reflect as well on what happened in history. The caliphate of Uthman is a crucial period in the history of early Islam, and we have to reflect why in spite of the eminence of Uthman, his caliphate was not as successful as it should have been, and why it culminated in the tragedy of the assassination of the Caliph?
"When a person dies, his works end, except for three: ongoing charity, knowledge that is benefited from, and a righteous child who prays for him."
Prophet Mohammed (PBUH)
"The best of what a man leaves behind are three: a righteous child who supplicates for him, ongoing charity the reward of which reaches him, and knowledge that is acted upon after him."
Sunan Ibn Mājah
"Every day two angels come down from Heaven and one of them says, 'O Allah! Compensate every person who spends in Your Cause,' and the other (angel) says, 'O Allah! Destroy every miser.'"
Sahih Bukhari
