Asalam Alaikum. My sister is a divorced. I have sadly found out my sister has a haram relationship with a married man. The mans wife is both my sisters and I very good friend so I could not believe my sister would do this to her. I’m so sad. What should I do? Tell my parents, tell my friend or confront my sister (she doesn’t know I know)?

Alaikumassalam wa rahmatullah,

Sorry about your situation. It would be best to confront her privately without any threats of letting others know about it. Maybe this will make her agree to end the relationship. If she does not, then you can tell her that you will tell your parents and your friend who is being cheated on.

It is best to try to solve such matters as privately as possible, since this is best for everyone involved.

Even if your sister promises to break the relationship, there is of course still the fact of your friend being married to such a man. I cannot say what should be done about this, for example if children are involved then that would complicate matters. If there is a chance that the man may repent and go on with his life like normal then it might be best if your friend does not find out about his cheating. If you are unsure what to do in this regard, it may be best to leave it to God to decide what He wishes. But if you get a clear sense that it is your duty to tell your friend, then perhaps consult a knowledgeable person you trust who knows you and knows that family and maybe a solution would suggest itself.

Best wishes.
