I ask that there be no debates on this thread. I want only clarification of the positions scholars hold or have held. Thank you all for respecting my wishes.
Here are the positions as I have understood them.
(1) [Murabitun] Paper money was haram when it originated, and it has the same nature now so the default ruling or the 'asl remains that it is haram. It is however permissible in our times because of necessity.
(2) [Deobandis] Paper money was haram (or makruh tahriman) when it originated, but because of the way it is now being used its nature has changed and hence it is no longer haram.
So did I get these positions right?
