Uthman, Othman, Osman, Usman, or Ozman (Arabic: عثمان) is a male Arabic given name meaning "the chosen one amongst the tribe of brave and noble people", "honest", "caring", "sincere", "genuine", and "attractive". The tughra (stylized signature) of Sultan Mahmud II of the Ottoman Empire. ...
Uthman is credited for having centralized the administration of the Muslim state, and it was during his reign that the compilation of the Koran was completed.
Uthman was the last caliph who could enjoy unity in the Muslim world, even if there was much displeasure with his regime.
Through his weakness, Uthman became one of the most important men of early Islam, paving for the first schisms in the religion, schisms that still exist (Sunni, Shi'i and Khariji).
Uthman was a member of the wealthy Umayyad clan; his early conversion is noteworthy since most members of his clan did not convert until the conquest of Mecca in 630.
Uthman appears to have played only a small role during the lifetime of Muhammad and the caliphates of Abu Bakr and Umar.
Uthman was chosen caliph by a six-member comittee in 644.
