Islam in China
According to traditional Chinese Muslim accounts, the history of Islam in China began when four "Ṣaḥābā"—Sa‘d ibn Abī Waqqās (594–674), Ja'far ibn Abi Talib, and Jahsh preached in 616/17 and onwards in China after coming from Chittagong-Kamrup-Manipur route after sailing from Abyssinia in 615/16. Sa‘d ibn Abi Waqqas again headed for China for the third time in 650–51 after Caliph ‘Uthman asked him to lead an embassy to China, which the Chinese emperor received warmly.
