Does a wife's disobedience to her husband in matters commonly known (to be obligatory) constitute a transgression of Allah's boundaries?

A wife's obedience to her husband is obligatory and is considered more binding than her obedience to her parents. Disobeying him in matters where obedience is due is considered nushuz (rebellion), which is forbidden and a violation of Allah's sacred limits, especially if she refuses to share his bed without a legitimate Sharia-compliant excuse, for which the angels curse her until she awakes.
