Is it permissible for a wife to wear a piercing in her navel to adorn herself for her husband?

Piercing the navel and adorning it with jewelry is impermissible because it constitutes an assault on the body and a form of torture. Since it is impermissible, obedience to the husband in this matter is not allowed, as the Prophet, peace and blessings be upon him, said: "There is no obedience in disobedience; indeed, obedience is only in what is right."
