Peace be upon you. According to Grand Ayatollah Sayyid Sistani (may Allah protect him): If her voice, with its refinement and enhancement, is typically enticing to the listener, even if the listener is a mahram (non-marriageable relative), it is necessary to avoid that, ensuring that men do not hear her voice; otherwise, there is no harm in it. Caution should be exercised in cases of doubt, and it is preferable not to make her voice heard without necessity. And Allah is the protector.
