What is meant by "that which relates to marriage and its ancillary matters" as a condition for a wife's obedience to her husband?

A woman is not obligated to obey her husband in everything he commands, but only in matters related to marriage and its

consequences. However, the more authoritative opinion is that it is obligatory to obey the husband in everything he

commands his wife, as long as it does not involve disobedience to Allah or harm to her, even if it is not related to

marriage.
