What is the ruling on dealing with relatives who are characterized by malice, betrayal, and the spread of rumors, especially after one of them assaulted my daughter, stole my money, claimed that I was the cause of his imprisonment, and then divorced my daughter?

You should be keen on your daughter's future and marry her to someone known for his religious commitment and righteousness. If the husband meets the described criteria, it is advisable to be patient until the 'iddah period ends to avoid harm. As for the relationship with relatives, you must treat them kindly and avoid anything that incites animosity. It is permissible to reduce meetings with them if harm results from such meetings. Regarding financial rights, you have the right to claim them judicially if you have evidence.
