Welcome to the Wefugees Community and thank you for your question.
I assume you are staying in Germany? As far as I know, marriages here are only recognized and valid in a legal sense if they were registered in the registry office (“Standesamt”) and not when they are “only” committed in the mosque (Islamic marriage). If you are legally married you might have the chance to apply for a family reunification visa for her. You are a recognized refugee here?
In any case, some more details on your situation will be helpful to share tailored information.
Please get back to us if you want to discuss your case further.
All the best,
