Wartime experiences, particularly his outrage at the Sétif massacre of May 1945, also inspired Aba to commit to writing more poetry. His work is primarily focused on themes relating to politics and the impact of violence on humans, covering topics such as the Algerian revolution, the Arab–Israeli conflict and Nazi Germany. The themes of his work led the scholar Jean Déjeux to compare him to Mohammed Dib. Aba's more well-known collections include "Gazelle au petit matin" ("Gazelle in the Early Morning", 1978) and "Gazelle après minuit" ("Gazelle after Midnight", 1979), which take the form of a series of love poems inspired by the deaths of a young couple at the point of the country becoming independent from France.
