In principle woman’s work is permissible as long as the work itself is lawful and Islamically good and the surrounding circumstances and environment are Islamically healthy. In other words, woman is permitted to work provided that the following conditions are met:
First, the work should be legal. The Muslim woman is not permitted to work in a place where she will be in privacy with non-mahram (marriageable) man, or in clubs where she is supposed to offer alcohol to people.
Second, she should abide by the Islamic morals in dress, talk, etc.
Third, woman’s employment should not be at the expense of her principal work, namely caring about her children and husband.
Admittedly, the Muslim society is in need of working women in certain fields such as education and medicine in order to educate and treat women.
