Abstract
Interest prohibition theory concerns theoretical aspects of interest
prohibition.
We attempt to lay down some aspects of interest prohibition theory
wrapped in a larger framework of informal logic.
The reason for this is that interest prohibition theory has to deal
with a variety of arguments which is so wide that a limitation to
so-called correct arguments in advance is counterproductive.
We suggest that an application specific informal logic must be
developed for dealing with the principles of interest prohibition
theory.
