Like al Ghazali, al Kindi, and al Farabi for starters.
Great philosophers and theologians.
(btw, it's not a good idea to laugh at people who have more information than you do..........it just makes you look.................dumb).
And I won't doubt al Farabi's contributions to Islamic thought as it applies to some twisted form of political science. Although I would ask you exactly how al Farabi's sense of a perfect society would be Muslim and one of its main purposes was bringing about salvation of the citizens applies to 'freedom'...
I can't speak on al Ghazali as the name is not familiar, although I will research it and get back to you
