Wartime experiences, particularly his outrage at the Sétif massacre of May 1945, also inspired Aba to commit to writing more poetry.[2] 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.[2][5] The themes of his work led the scholar Jean Déjeux to compare him to Mohammed Dib.[4] 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.[5][6]
