The ruling on boycotting a woman because of her problems with her brother's wife?

Question:
I ask Allah to do you good. The letter from J.M.H. from Jeddah says in her first question: I have a problem, Honorable Shaykh. My brother's wife has caused many problems between her and people, and because of that, she has put my brother in an awkward position with them. We used to advise her, but she did not respond. My brother has been harmed by her, as she has saddled him with many debts and given him a bad reputation among people. We have boycotted her; we do not visit her, and we do not like her to visit us. Is what we did correct? Is it permissible in the Shari'ah? And what do you advise?

Answer:
If a woman is bad in her actions, or in her religion and conduct, she must be advised first. If she does not comply, and boycotting her serves as a deterrent and a check on her, then she is to be boycotted. However, if boycotting her only leads to more evil, then she is not to be boycotted, but the advising continues, in the hope that Allah will guide her. Yes.
