thank you for sharing your situation with us.
As for your question:
Under the Dublin Regulation the authorities consider family relationships, and yours the immidiate family member( as a wife):
So they will not deport him if you can proof that you are in a relationship and have applied for marriage in Germany.
In regards of the question addressing the passport- if he has cliamed political asylum then he will not be send to his embassy and might be able to obtain the so called "Grey- Passport" (Ersatzpass) from Germany. But this depends whether his claim will be believed upon.
I hope we could assist you, if you need further guidance please do let us know.
