What is the ruling on disliking what is permissible and mocking it, and does the same ruling apply to disliking polygyny, given that it is permissible?

Disliking polygyny or mocking it as a religious ruling falls under disliking what Allah has revealed, which is an act of disbelief (kufr), based on the Almighty's saying: "That is because they disliked what Allah revealed, so He rendered their deeds worthless." However, disliking it due to natural inclination, stemming from the jealousy and desire for exclusivity inherent in human nature, while still accepting and submitting to the religious ruling, is not an act of disbelief.
