A Muslim girl has been married for 5 years. Her friend did another (last) istikhara without the wife’s knowledge and she told her it was “bad”. This was told to her despite the wife’s request to not tell her the result. Does the wife have to act on the istikhara and divorce? Should she do another istikhara herself to confirm the result?

All what she did is nonsense. No body has the right to do istekhara for others without their request
