What is the correct course of action regarding two daughters who wear the hijab and are subjected to insults in Western countries, which has negatively affected their psyche and their refusal to go to school, four years after this situation began?

The default ruling is that a Muslim is prohibited from residing in non-Muslim lands due to the danger this poses to their religion and morals. However, residence is permissible if the Muslim can openly practice their religious rituals and is secure from temptation, for the purpose of achieving a religious or worldly benefit.

If girls are subjected to harm because of the hijab, the advice is to leave these lands and return to a Muslim country, or to search for suitable Islamic schools and connect with righteous women. If you are unable to protect your daughters and fear temptation for them, then it is not permissible for you to remain, and you must emigrate.
