In Islam, it is permissible for the woman to work outside the home as long as she sticks to the Islamic manners while going out. However, this ruling of permissibility can’t be generalized as each woman has her life priorities and can arrange those priorities according to that.
The London-based da`iyahZienab Mostafa states the following: Islam considers women equal to men in humanity and in all aspects of human rights. The woman’s right to work is permissible in principle, but we cannot give a general rule for all women. Every woman has her priority and can arrange her life according to that.

Women’s work can be obligatory for her if she does not have anyone to look after her and she is able to work and earn her living in a lawful way. It could be forbidden if her work would lead her to neglect her duty as a wife and as a mother. It is entirely lawful and allowed if the woman can strike a balance between different duties and obligations.
We cannot forbid women from work and deprive the society from the benefit and knowledge that they have, under the pretext that Islam forbids women to work, which is completely baseless. If we return to the seerah (biography) of the Prophet (peace and blessings be upon him) and his Companions, we will find that they lived a happy life when men and women worked together to fulfill their duties.
