In October 1934, Jahan married "Angaaray" collaborator and noted Communist Mahmuduz Zafar. Jahan resigned from the United Provinces medical service and joined Zafar in Amritsar soon after. In 1935 and 1936, Jahan was intimately involved in the founding of the Progressive Writers' Association, organizing the First Progressive Writers' Conference in Lucknow during the April of 1936. In 1937, Jahan moved once again, this time to Dehradun, where she continued to be an active member of the Communist Party of India while working as a gynecologist and serving as the editor of the Communist newspaper-cum-literary journal "Chingari". In early 1937, Jahan published a collection of plays and short stories entitled "Aurat". In the summer of the same year, Jahan travelled to Vienna to seek medical aid for a thyroid problem.
