What is the ruling on a woman working in a mixed-gender environment while adhering to Islamic guidelines, and is that considered a sin, especially given the instances of women participating with men in some situations during the time of the Prophet, may Allah bless him and grant him peace?

A woman's work involving mixing with non-mahram men while her face and palms are uncovered is forbidden, according to the correct opinion among scholars, which states the obligation of covering the face and palms from non-mahram men, and the prohibition of mixing with them. However, it is permissible for a woman to go out for a need, such as jihad or prayer, provided she adheres to the hijab and Islamic guidelines.
