What is the ruling on boycotting relatives who bring nothing but harm?

Question:
From Sudan, our sister asks in her own way about the ruling on cutting off relatives who bring nothing but harm, and who are afflicted with bad traits. She tried to reform them but could not. What is the guidance of Shaykh Salih? May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. All praise is due to Allah, Lord of the worlds. May Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and his Companions. To proceed: There is no doubt that those with kinship ties have a right that Allah the Exalted has made obligatory. He the Exalted said: He the Exalted said: So the relatives have a right to be treated with kindness.
And to be kind to them. Being kind to them, and maintaining ties with them, is part of that. Indeed, the greatest of that is advising them if he sees in them something that is not befitting their religion or their morals. So it is their right upon him to advise them, and they are the most deserving of people of his advice. He the Exalted said: He the Exalted said: So they are the closest people to him and the most deserving of his advice if he sees in them something that compromises their religion, their honor, or their morals. If he sees acceptance from them, praise be to Allah, and he will have benefited them and been kind to them. If he does not find acceptance from them, he has absolved his duty, established the proof against them, and fulfilled what is obligatory upon him, and he does not have the power to guide them. He the Exalted said to His Prophet: And if mixing with them and sitting with them is harmful to a person’s religion, such that he fears they will influence him, then he should avoid them to preserve his religion, and boycott them to the extent of the need, and continue advising them, and not despair of their guidance, perhaps Allah will guide them, or perhaps his boycotting them will affect them, so they repent to Allah the Mighty and Majestic. Indeed, boycotting is prescribed if there is a benefit in boycotting in religion, if there is a benefit in that it affects the one being boycotted. But if it does not affect the one being boycotted, and rather it may increase him in evil, then he should not boycott him, but rather continue advising and admonishing him, perhaps Allah will guide him, and the advisor’s duty is absolved by that. Yes.
