Wife Changing Math-hab

Q: Is it permissible for a woman to change to the math-hab of her husband?

A: Changing the mazh-hab for the reason stated in the question is not permissible, since a couple may live harmoniously in spite of difference in mazh-hab. There are only a few areas which demand some caution between Shafi’ee and Hanafi, such as touching each other, for this breaks wudhu, and laws pertaining to iddat and talaaq. If and when the latter situation arises (Allah forbid), consult your local Ulema for guidance. If one is living in a place where only one mazh-hab is prevalent and there is no one to teach the other mazh-hab, then common sense demands that it is necessary to change to the prevalent mazh-hab in order to make amal on the Laws of Shariah. Otherwise, each one should adhere to his or her mazh-hab.
As for the children, the parents should decide before hand which mazh-hab they shall follow. In making this decision, consider convenience of madresa and Deeni tuition, as alluded to in the previous paragraph.
