What is the Sharia ruling on what should be done regarding a father's harassment of his sons' wives?

To deal with a father's harassment of his son's wife and his brother's wife, measures must be taken to prevent evil, such as the wife adhering to modest dress, avoiding seclusion with the father, and showing aversion and anger at his actions. The father should be advised if he goes too far, and if he persists in his shameful acts, the wives must be removed from his house to prevent further wrongdoing. Despite his actions, his right to filial piety remains, and part of filial piety is to prevent him from committing this evil. Increase your supplications for his guidance and righteousness.
