Bigiev welcomed the February Revolution, claiming that "slavery is gone, and will never come back". Even after the takeover by the Soviets, he saw the new regime as a potential ally against what he perceived to be the primary enemy of the Muslims of the world – the British Empire. During the course of the Russian Civil War, Bigiev toured the Volga region together with Abdul Hafiz Mohamed Barakatullah in order to mobilize the Muslim population for military service against the British. He also held close contact with other anti-British Indian activists and arranged for them to live in the Soviet Union.
