friends

Dear scholars, As-Salamu `alaykum. I was wondering whether you can help me with the following problem. Is it allowed for a husband to prevent his wife from allowing non-Muslim female friends, whom she had even before marriage, from entering the house? Also, is it okay to demand that the children not be allowed to have non-Muslim friends? Thank you.

As-Salamu `alaykum I have had a burden on my mind for a number of weeks now. Someone close to me is doing illegal, dangerous and unmoral things for a living, for example dealing unlawful drugs. I have spoken to them on many occasion and have explained to them the dangers of what they are doing, but they have refused to listen.the question I would like to ask you is, would it be morally correct for me to report them to the police? I want to report them but I am fighting with my morality, I don?t want to feel like I have ruined their life by sending them to prison but on the other hand I want to report them for their own safety, Allah sees all, and Allah sees I don?t want them to get hurt.Your advice would be appreciated
