After a distinguished military career, Khan served as Governor of Sindh during 1984–87 time period under General Zia Ul-Haq regime. Earlier in 1965–66, he was Military Secretary to the then Governor of West Pakistan, Nawab Malik Amir Mohammad Khan. He wrote a book, "Pakistan Leadership Challenges", in which Nawab Malik Amir Mohammad Khan comes across as a sound, no-nonsense administrator, firmly wedded to the values and traditions of the feudal class. He was also condidered "brutal", "ruthless" and "harsh" in both his public and private life. British assessment of the Nawab of Kalabagh was very similar. In his book, Jahandad,Nawab Malik Amir Mohammad Khan's Military Secretary dismisses alleged rumours about a somewhat sinister aspect of the Ayub regime. In 1963, the regime faced strong opposition from the political party Jamaat-i-Islami. Ayub himself "felt gravely threatened by its head, Maudoodi". "Some sycophants" sought to persuade Ayub that "the physical elimination" of Maulana would bring peace to the country and that Malik Amir Mohammad Khan was to help execute this attempt. Jahandad Khan dismisses this as a baseless rumour in his above book.
