Is disavowal in the heart sufficient if disavowal with the tongue is impossible?

Question:
He says: Honorable Shaykh, may Allah grant you success. A woman asks, and she says: It is not hidden from your honor what the state of Muslim women has become regarding tabarruj (display of adornment) and exposing the body. Unfortunately, disavowal has become difficult because of the physical and moral harm that befalls the one who disavows. So, is disavowal in the heart sufficient?

Answer:
Disavowal is not impossible with a Muslim woman. One can advise her and warn her of Allah (Mighty and Majestic). If she accepts, praise be to Allah. If not, the responsibility of the one advising, whether male or female, is cleared. So, disavowal with the tongue is not impossible, praise be to Allah. One advises the one who errs or sins. If a woman is bad in her hijab, one advises her. If she accepts, praise be to Allah. If not, the responsibility is cleared. Yes.
But if it is not possible with the tongue. For example, if you speak about the hijab, they cut your tongue, as is the case in some tyrannical regimes and oppressive countries. In that case, there is an excuse. But as long as one is not reprimanded or punished, no one is prevented from giving advice. Yes.
