Is it permissible for the author's maternal aunt to sell her literary story to be transformed into a television series, and what is the ruling on the money earned from that, and does she bear the sin of the actors' portrayal of the story?

It is permissible to write purposeful stories and tales that convey lessons and education, even if they are fictional, as long as their aim is to invite to virtues and avoid vices. It is permissible to receive financial compensation for their dramatization, provided that the dramatization does not include any forbidden acts, such as unlawful intermingling (ikhtilat) or the baring of 'awrah (private parts). Otherwise, the writer would be complicit in sin for cooperating in sin and aggression. In this case, the money received would be unlawful, and it must be disposed of by spending it on charitable and good causes.
