As a final-year student at the Turkish Military Academy (1938), he was arrested with Nâzım Hikmet and sentenced to ten months in prison.
[2] Having shared a cell with Nâzım Hikmet in Ankara Prison, A. Kadir was initially heavily influenced by this poet.
His first book, Tebliğ, which expressed his love for his country, openly opposed war and realistically reflected the lives of poor people.
He and Abdülbaki Gölpınarlı translated Rumi's poems from Persian into prose and compiled them into a book titled Mevlâna in Today's Language (1955).
His work 1938 Military Academy Incident and Nâzım Hikmet (1966) is also a book of great interest for shedding light on an important event of that era.
