Nissaboury was one of the co-founders of the magazine Anfas/Souffles ("Breaths"), an avant-garde bilingual quarterly that published essays, poetry, and fiction. (The magazine was banned in 1972.[3]) Together with Mohammed Khaïr-Eddine, Mostafa Nissaboury wrote the manifest "Poésie Toute" in 1964, an important milestone in the history of Moroccan literature.[4] In Casablanca he opened a house solely devoted to poetry. His works contributed much to the renewal of Moroccan poetry.[5]
