Dr. Buti says that in cases of Daroora for minorities, we should not invent a new fiqh, because the general principle still remains the reference for all times and all places.
Dr Ramadan Al Buti is a scholar whom I respect very much. As such, it would be useful for me, if you could give a reference of Dr Albuti's opinions.
My response is not to debunk what Dr Albuti *may* have said and meant. Rather, it is a response to show a variation of opinions in Fiqh based on specific context et al. Yes, the principles of shariah is perfect and suitable for all times, but the application of shariah is fluid and dynamic.
The Fiqh of Minorities, in my very limited sessions with those who are more knowledgable than me, is not a new fiqh. Muslims have been minorities in many societies throughout the world for centuries, and the fiqh dealing with such issues is not a newly (or oldly) invented one. What is "recent" about it, is simply terminologies.
As for Sr JO's case, I'd suggest more research and the usual "go back to an sheikh whom you trust" for a fatwa that's contextual for the sister's specific case, bearing in mind Br Abdurahman's reminder:
"..the Prophet, peace and blessings of Allah be upon him, used to say: "Ask your heart. Truth is what finds comfort in the heart, and falsehood is what is uncomfotable, even if the people give you so many fatwas."
