Is it permissible for a Muslim woman to uncover herself in front of her Christian neighbor, or is it not permissible for her to uncover anything except her face and her hands?

The questioner: My Shaykh, here is another question regarding the Christian woman. We know that it is not permissible for a Muslim woman to appear before her except with her face and hands uncovered. A woman describes a specific situation for herself, thinking that perhaps there is another, exceptional ruling for her. She says: She has a Christian neighbor, door to door, as they say. This Christian woman’s husband is Muslim and her children are Muslim and they pray, but the wife is Christian. And due to the proximity, she does not mean that she can do without receiving her or knocking on her door at every moment.

The Shaykh: Like her male neighbor, like her male neighbor.

The questioner: There is no difference, may Allah reward you.
