When Is Income Earned Be Categorized As Haram?
If you are thinking of selling sex dolls by openly displaying them in public in a state of nudity, of course that is not allowed sir. Of course, when selling them in public, they wear clothes on the sex dolls; it is impossible to openly display sex dolls without clothes in public. But once they have been purchased… well, that is a private matter.
In that case it will not be Haram but still discouraged.
