Uthman Ibn Affan - Reign As A Caliph (644–656)

Reign As A Caliph (644–656)

On assuming office, Uthman issued a number of directives to the officials all over the dominions, ordering them to hold fast the laws made by his predecessor Umar. Uthman's realm extended in the west to Morocco, in the east to South east of present day Pakistan, and in the north to Armenia and Azerbaijan. During his caliphate, the first Islamic naval force was established, administrative divisions of the state were revised, and many public projects were expanded and completed.

Uthman sent prominent sahabas ("companions of Muhammad") as his personal deputies to various provinces to scrutinize the conduct of officials and the condition of the people. In total, Uthman ruled for twelve years. The first six years were marked by internal peace and tranquillity, and he remained the most popular Caliph among the Rashidun; but during the second half of his caliphate a rebellion arose.

Uthman had the distinction of working for the expansion of Islam, and he sent the first official Muslim envoy to China in 650. The envoy, headed by Sa`d ibn Abi Waqqas, arrived in the Tang capital, Chang'an, in 651 via the overseas route. The Hui people generally consider this date to be the official founding of Islam in China. The Ancient Record of the Tang Dynasty recorded the historic meeting, in which the envoy greeted Emperor Gaozong of Tang and tried to convert him to Islam. Although the envoy failed to convince the Emperor to embrace Islam, the Emperor allowed him to proselytize in China and ordered the establishment of the first Chinese mosque in the capital to show his respect for the religion. Uthman also sent official Muslim envoys to Sri Lanka.
