A woman working among females

Q: My wife works at a university in the female students' department and does not mix with men. She wears a garment that covers all her body including her (Part No. 17; Page No. 234) face. She works in the library in the faculty of Shari`ah and Islamic studies for female students. Is it permissible for her to work in this job?

A: If the reality is as you mentioned, there will be no harm on her to continue working in this job. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
