What is the ruling on disobeying parents if they have falsely accused their son of fornication and immorality and incited people against him?

Oppression by a close relative has a profound impact, and one must be patient and seek reward from Allah. Whoever maintains ties with their abusive relatives, Allah will help them overcome them, as it is stated in the noble hadith that whoever does so is as if they are feeding them hot ashes, and they will always have a supporter from Allah. One should repel their evil with kindness, for good deeds repel evil and turn an enemy into a friend. One should also pray for the rectification of their parents' and siblings' situation, and seek help from someone whose word is heard to reconcile between them. And let it be known that if one fears Allah and is dutiful to their parents, their parents' disownment and unjust displeasure will not harm them.
