The theme of the story "The Djinn who lives between night and day" would be that not all lies are bad. In the story al-faq lied to the husband saying that his wife and kids were still alive when they weren't, but it made the man feel happier even though he was still sad because he would never see his wife and kids again. A real life application would be when parents and teens lie to each other either to get out of trouble or to keep each other safe.
