Douagi's most lasting contribution to Tunisian literature, as well as pan-Arabic literature, are his short stories that were collated and published in 1969, twenty years after his death, into a single anthology entitled "Sahirtu minhu al-layali" ("Sleepless Nights, 2000").[6] On May 27, 1949, Douagi died of tuberculosis.[7] According to many accounts, he was abandoned by many of his friends and harboured bitter disappointment for not being recognised for his work.[7] However, on the tenth anniversary of his death, Zin al-Abidin al-Sanusi published an article entitle "al’Du’aji’s Legacy" which resurrected critical inquiry and public interest in his work.
