What is the consequence of not being content with Allah's blessing of a good and generous husband?

A righteous husband is a great blessing. Gratitude for this blessing is expressed in five ways: the grateful person's submission to the one thanked, their love for him, their acknowledgment of his blessing, praising him for it, and not using it in ways he dislikes. The wife's dissatisfaction with this blessing is feared to be a denial of it, and denying a blessing is among the causes of its removal, as happened in the story of the village that denied God's blessings, so God made it taste the garment of hunger and fear. The woman might also be replaced with an unrighteous husband who does not treat her well.
