Dear s1c4r1us,
It does not as far as I know. Immigration to Abbasinia is part of the sirah (Biography of the prophet). I was asking about maybe an implicit reference from the Quran that sanctions a model where believers can stay as a minority in non muslims lands. And whether such a model would go against verses that speak against taking unbelievers as guardians ? I am just stating Abbasinia as an example of that happening in muslim history. But its important to note that muslims back then had no other choice.
Regards,
