What is the ruling on a wife cursing her husband by saying, "May Allah curse you, the curse of the Christians and the Jews"? And does that affect the continuation of the marital relationship?

Cursing a specific Muslim is a grave sin, as the Prophet, peace and blessings be upon him, said: "Cursing a believer is like killing him." The matter becomes even worse if the cursing is from a wife towards her husband. Therefore, the wife must repent to Allah and seek forgiveness from her husband. This cursing does not affect the marital life or lead to divorce.
