The ruling on associating with neighbors when their condition is unknown

Question:
If one does not know the condition of the neighbors, should he isolate himself from them and then study their conditions before associating with them?

Answer:
He should study the conditions of the society and look at the public benefit. If the public benefit requires admonishing them, reminding them, and associating with them, he does so. If he sees that the public benefit requires isolating himself from them, he isolates himself from them. He must look at the matter that has occurred among the people, for people are in need of guidance, direction, and education, as well as enjoining good and forbidding evil. However, if there is no way to deal with the matter, let him isolate himself.
