Towards the end of Abu'l-Khair's rule, Nasrullah was promoted to commander of the Muslim Kazakh ghazis.
He also earned the title Bahadur (braveheart) due to his combatting prowess and rise in the military ranks.
While the uprising was unsuccessful, Nasrullah and Nur Ali survived and went on to lead the Kazakhs for approximately thirty more years.
Following the failed rebellion against Russian settlers, Nasrullah Bahadur spent the rest of his life aiding Kazakh ruler Abu'l-Mansur Khan as a commander in the Kazakh-Dzungar Wars and in battles against the expanding Qing Chinese.
After displaying abundant bravery in battle, Abu'l-Mansur made Nasrullah one of the three standard-bearers in the Kazakh army.
