He participated in some diplomatic missions on behalf of Kazan khans to Muscovy and there carried out negotiations for the khanate's independence.
In 1552 he was one of leaders of Kazan's defense from the Russian troops of Ivan the Terrible. He also participated in the negotiations with Russian representatives in Sviyajsk ( Zöyä). After the storm of Kazan started, he organized a group of students and defended the Khan Palace. He was killed during the battle.
