Born to an anti-colonialist family in Hyderbad, Abid Hasan was brought-up in India and later went to Germany to train as an Engineer. It was while he was a student in Germany during World War II that Abid Hasan met Subhas Chandra Bose and decided to join the Indische Legion. Hasan would later serve as Bose's personal secretary and interpreter while Bose was in Germany. Hasan also sailed with Bose in the German U-BoatU-180 in 1943 in Bose's voyage to South East Asia. Over the course of the reformation of the INA and its campaigns in the south east Asian theatre, Hasan rose to be a Major in the Azad Hind Fauj. It was also during this that he adopted "Safrani", after the holy Hindu colour of Saffron, to his name as a mark of communal harmony.
After repatriation to India at the end of the war, Abid Hasan was released following the end of the INA trials in 1946 and joined the Indian National Congress briefly. After partition, Hasan chose to settle in Hyderabad and joined the nascent Indian Foreign Service. Over a long diplomatic career, Hasan served as the Indian Ambassador to a number of countries including Egypt and Denmark before retiring in 1969 and settling in Hyderabad. Abid Hasan Saffrani died in 1984. According to Leonard Gordon the author of Brothers Against the Raj, Abid Hasan Safrani coined the salutation "Jai Hind" (Hail India). It was the shortened form of "Jai Hindustan Ki". The term was made famous by Netaji Subash Chandra Bose's INA and its subsequent use as a national patriotic salutation in independent India. Netaji Bose's nephew Aurobindo Bose later married Safrani's niece.
