Is the hadd punishment obligatory for someone who said to his wife: "You daughter of a haraam"?

Uttering "ya bint al-haram (definition)" (daughter of the forbidden/unlawful) to one's wife or anyone else is an accusation against her parents, and it is among the seven grave, destructive sins. Allah has threatened those who accuse with curses and a great torment in this world and the Hereafter. If the matter is brought before the ruler without proving the accusation with four witnesses, the accuser is punished with eighty lashes, and his testimony is never accepted. Whoever has accused must repent to Allah with sincere repentance.
