Starting his political career in 1934 with the Indian National Congress, Khan quickly rose to serve as an elected member of the Central Legislative Assembly (1937–38) and the deputy leader of the Congress in the Assembly. At that time he admired Khan Abdul Ghaffar Khan. He authored a book, Gold and Guns on the Pathan Frontier,[8] in which he praised Ghaffar Khan and denounced Jinnah and the two-nation theory.
