The ruling on a woman wearing a mask over her mouth and nose during Hajj and 'Umrah

Question:
The sister Umm Muhammad says: Shaykh, in this question, my sister wears a mask over her nose and mouth during 'Umrah and Hajj. Is there any harm in that? Because she has an allergy?

Answer:
The woman in the state of ihram is prohibited from wearing the burqu' (face veil) or the niqab (face veil), or anything sewn to fit the face or specifically for the face. As for anything else, there is no objection to her covering her face from men with the khimar (head covering) or the shaylah (scarf) she is wearing. There is no harm in that, just as the female Companions used to do so with the Messenger (peace and blessings be upon him) while they were in the state of ihram, as 'A'ishah (may Allah be pleased with her) narrated. And the mask, if she needs it, is not like the burqu' or the niqab, or what is sewn specifically for the face. Yes.
