Sadegh Hedayat is a well-known author whose reputation is mostly due to the modern stories and innovations in their content and themes. The short story of "Tomorrow" is one of his writings that has been underestimated. This story, which is considered a Proletarian literature, has a Marxist attitude in addition to the existentialist aspects. A study of the intersection of these two perspectives in this story helps identify the Marxist thoughts of Sartre as one of the existentialist thinkers. Sartre, who endorses and strengthens Marxism in some of his works, confirms the purposefulness of the world, which Marx believes in, while the existentialism considers the world absurd and meaningless. In this research, while introducing shortly Sartre's thoughts and his Marxist orientations, we investigate the story of "Tomorrow" from this perspective.
