Going out without the husband's permission to work or to visit others

Q 2: What is the ruling on a woman going out without her husband's permission to visit her female neighbor, her family, or to work?

(Part No. 19; Page No. 372)  A: It is impermissible for her to do so unless her husband explicitly permits her to go out. However, such permission may be implied by `Urf (custom) which is agreed upon by both of them or that there is a condition in the contract of marriage to the effect that a wife is to be given permission to work. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
