What is the legal ruling regarding a contentious divorce occurring before the court, given the prior claim of an irrevocable divorce that has not yet been decided, and what should the wife do in this situation?

Since the matter has reached the Sharia (definition) court and it has issued its ruling, the court has the final say. If the husband had irrevocably divorced his wife before consummation, or through khula (definition)', or through a revocable divorce whose waiting period (iddah (definition)) has expired, then the second divorce pronounced before the judge does not count. However, if he was untruthful in his acknowledgement of the divorce, then it is outwardly effective, but she remains his wife inwardly, and the divorce is binding upon her. A second divorce may occur if the first was revocable and the waiting period had not ended; in this case, she is considered to have been divorced twice, and her husband can take her back before her waiting period ends. The waiting period concludes with the purification after the third menstrual cycle, or after three months, or upon giving birth. If the total number of divorces reaches three, she becomes unlawful for him until she marries another husband in a valid marriage.
