What are the reprehensible acts that should be avoided when writing fictional novels, and is the failure of female characters in a novel to wear the hijab considered one of these reprehensible acts?

Writing fictional stories is permissible if they are free from Sharia-prohibited elements, such as promoting evil or beautifying vice. Merely describing women's feelings or clothes without images does not necessarily beautify immodesty. Jurists have permitted the poetic description of the beauty of an unspecified woman, as long as it does not become obscene.
