Assalamu Alaikum wa Rahmatullah
Imagine in the future there is a restored Sunni Caliphate of some form which becomes involved in a war with Rafidite Iran. Imagine the Caliphate defeats the Iranians but is left with a problems of over 50 million people, many of whom who are liable to try to restore twelver shiah rafidite rule to the country if left to their own devices.
Deobandi and Wahhabi Ulema both hold rafidites as being disbelievers therefore would it be lawful for proven rafidites to be enslaved like it is lawful to enslave disbelieving prisoners of war?
is there any existing scholarly work on the issue of whether it is possible to enslave a rafidite whose beliefs mean that he is not a Muslim even though he may call himself one?
and before any Shiahs on here get offended I am not suggesting that this should be done and neither do I think it would likely be a fitting thing for a Muslim to do with people who follow the Qur'an and the Messenger (saws) in a way, I am merely trying to understand what are the legal implications of these rulings from part of the Sunni Ulema.
and personally I doubt Allah would particularly be pleased with the one who tried to revive this institution, especially after good Muslims spent long centuries using their wealth to free slaves
