Maulana Imdad Sabri was one of the most ardent followers and a comrade of Subhas Chandra Bose. He remained in Congress and held important positions until Netaji was in Congress.
In 1938, at Haripura session he remained loyally with Netaji and joined the All India Forward Bloc. Several times he used to smuggle important information to Netaji, when he was under house arrest.
The British kept him in jail several times for his national services. In August 1945, he was again arrested for hosting the AHF officers and spies at his home in Delhi. He was charged for providing the logistic support to the Azad Hind Fauj in Delhi.
In Delhi jail, he met five Azad Hind Fauj soldiers, viz. Kanaul Singh, Sujit Roy, Sardar Kartar Singh, Shri Bhagwat Gautam Upadhyay, and Ram Dulare, who were sentenced to death for fighting against the British. Sabri mobilized public support for these five soldiers and the sentence was not carried out. All of them were released in 1947, after India attained dominion status.
He wrote several books like, Tarikh-e-Azad Hind Fauj, Muqadma Azad Hind Fauj, Azad Hind Fauj ka Album, Subhas Babu ki taqrire, Subhas Babu Japan kis tarah gaye etc. to dispel the false propaganda against Netaji and the Azad Hind Fauj. A journalist by profession, he devoted his energies in popularizing the war of liberation led by Netaji. Till his last breath in 1988, he never believed in ‘plane crash theory’.
