A woman sitting with non-Mahrams without being completely covered

Q 4: What is the ruling on a woman who wears Niqab (face veil) but displays her face before non-Mahram (not a spouse or an unmarriageable relative) men? Sometimes she sits with them and pours coffee in glasses for them. Moreover, she goes out with them. Her guardian is satisfied with her doing so. This bad habit is rampant in Shahran, Ghamid, Zahran and in the outskirts of Al-Qunfudhah as Huliy, Bayh, Fatuna, Lawmah and Al-Ahsiyah. Moreover, most of the people in the south that were mentioned above are guilty of this bad conduct.

A: It is not permissible for a woman to uncover her face before non-Mahrams. Moreover, she is not permitted to sit with them or go out with them. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
