Will the divorces my mother mentioned take effect despite her menstruation? What is my father's current situation regarding his relationship with my mother and his severing of ties with his sister, paternal uncle, and mother due to what was said about him and his wife? Is what my paternal uncle and grandmother said considered slander that necessitates the application of the prescribed punishment (Hadd)?

Your father's divorce pronouncements varied; some were explicit, and some were implicit. Each pronouncement has its own ruling depending on the wife's state (whether consummated, not consummated, or during her 'iddah (definition) period, or otherwise). Any divorce that occurs after the three pronouncements have been exhausted is considered null and void. If the marital relationship did not end with the three pronouncements, your father must renew the marriage contract in the presence of a guardian and witnesses. He must also repent and frequently seek forgiveness. His children from her are legitimate as long as he believes the marriage to be valid.

It is not permissible for your grandmother and uncle to delve into the honor of your father and his wife. Likewise, it is not permissible for your grandmother to relay conversations between her children, as this constitutes backbiting. Your father must honor his mother and not abandon her, just as it is forbidden for him to abandon his brother. You must honor your father, your grandmother, and your uncle. What your uncle and grandmother said about your mother being forbidden to your father does not constitute slander that necessitates a prescribed punishment (hadd). Regarding Sheikh Ibn Baz's fatwa (definition), it cannot be discussed due to a lack of knowledge of its circumstances. It is advisable to consult a Sharia (definition) court or trustworthy scholars to detail the situation.
