To what extent is an appeal admissible after a judgment of divorce due to harm, knowing that there are two witnesses who testified to the beating and insults and presented their testimony before the judge?

A judge's ruling on divorce, if based on sound Sharia principles, is considered valid and cannot be overturned or appealed. This is because a judge's ruling resolves the dispute. A ruling is only overturned if it contradicts a clear text from the Quran, Sunnah, a consensus (Ijma'), a clear analogy (Qiyas), or universal legal principles. This is because overturning judicial rulings leads to unresolved disputes and ongoing litigations.
