Must a husband clarify matters of Islamic law to his wife to avoid disagreements?

Seeking knowledge is an obligation upon every Muslim man and woman. A woman must learn what corrects her creed and worship, and what she needs concerning transactions. If she is married, her husband must teach her or enable her to learn. It is permissible for her to go out to seek essential knowledge that she cannot find with him. The couple's understanding of the religion helps in solving marital problems with justice and fairness.
