The financial support of a woman is the responsibility of her husband. If he is poor, his wife's brothers can give him part of the Zakah due on their money to spend it on himself, his wife, and his dependents. Brothers of this wife can give her part of the Zakah due on their money to spend on herself, her poor husband, and their children. Moreover, if this woman has money on which Zakah is due, she can give Zakah of her wealth to her husband to spend it on his dependents.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
