Short answer
A woman should not be treated as financially responsible for supporting the household merely because she is educated or employed.
Islamic Guidance
What Islam teaches
Islamic financial responsibilities in marriage should be understood according to Islamic law. A woman's wealth and earnings belong to her, while arrangements for employment and household finances should be discussed respectfully.
Practical Guidance
What you can consider
Discuss employment plans, household responsibilities, childcare and financial contributions before Nikah. Do not assume that employment automatically means surrendering personal income.
