What is the ruling on a veiled wife traveling abroad, and is it permissible for her to uncover her face at the airport or when traveling to another city if the hijab is prohibited? And is it permissible to emigrate to Turkey?

Covering the face for women is obligatory, but it is permissible for her to uncover it when there is a need to remove hardship and difficulty, such as avoiding fears or exposure to harassment, due to the Almighty's saying: "And He has not placed upon you in religion any difficulty" and "So fear Allah as much as you are able." When the need ceases, it is obligatory to return to the original ruling, which is covering the face. It is permissible for a Muslim to emigrate to a Muslim country where he can establish the rituals of his religion without hardship.
