He earned the title Iwaz Khan from Emperor Aurangzeb of the Mughal Empire and served as the Faujdar of Berar under the patronage of Mir Jumla III, maintaining this position until 1724.
Subsequently, he allied with his nephew Nizamul Mulk, providing crucial support in various conflicts against the Mughal Empire and the Sayyid Brothers, a pivotal role in the establishment of the Asaf Jahi dynasty.
Recognizing his contributions, Nizam appointed him as the prime minister of his dominions and elevated his Mansabdar to 7000/7000, granting him the prestigious title of Amir-al Umara of the realm.
He continued in his role during Husain Ali Khan's tenure as Subahdar until Nizamul Mulk rebelled against the Sayyid Brothers, marching from Malwa.

This successful defense contributed significantly to the defeat of the Mughal forces and led to the establishment of the Asaf Jahi dynasty, marking the independence of the Nizam.
[7] As part of efforts to consolidate power, the Nizam sent an army commanded by Iwaz Khan to the Carnatic region in 1725, with the aim of suppressing Maratha revenue collections.
