Is the daff (tambourine) the only permissible musical instrument, and is listening to it restricted to women and only during Eid and celebrations, or are there other prohibitions?

The basic rule regarding the use of musical instruments is prohibition, except for what has been explicitly permitted, such as the duff (tambourine). It is permissible for women to use the duff during Eid, weddings, and upon the return of a traveler. Anything other than that remains subject to the original ruling, which is prohibition. It is not permissible for men to use the duff or any musical instrument, as that constitutes imitating women, and it is a major sin.
