Hostility to Christianity was espoused by the Committee for National Revolution. The Bughras applied Shari'a while ejecting the Khotan-based Swedish missionaries. They demanded the withdrawal of the Swedish missionaries while enacting Shariah on March 16, 1933. In the name of Islam, the Uyghur leader Amir Abdullah Bughra violently physically assaulted the Yarkand-based Swedish missionaries and would have executed them all, but they ended up only being banished thanks to the British interceding in their favor. There were beheadings and executions of Christians who had converted from Islam to Christianity at the hands of the Amir's followers. The missionaries faced hostility from the Uighur leader Muhammad Amin Bughra.
