Islam was the professed religion of the Sibir Khanate; it was the religion of the ruling Khan of Tyumen and Sibir. Grand mosques, palaces and fortified walls were constructed by the ruling class in both Tyumen and Sibir.

Islam was professed by not only the Khan but also the Mirzas, who were often educated in famous Islamic centers in Central Asia like Bukhara and Samarkand. However, shamanism and other traditional beliefs were practiced by much of the masses. Some groups practiced a form of Islam that incorporated elements of shamanism.

The leading Imams and Muftis of the Sibir Khanate are known to have had some influence in Kazan and Samarkand. The Khanate of Sibir was the northernmost Muslim state in recorded history.

The Khanate of Sibir had extensive trading connections with Central Asia and the Khanate of Kazan.
