It is however recognized that the same standard as is applicable to conventional banking cannot be made rigorously applicable to an Islamic banking framework. Designing a comprehensive set of standard regulatory prescriptions and supervisory norms for an Islamic banking framework that are valid for all countries is a task yet to be accomplished.
A prominent obstacle in the accomplishment of this task is the lack of uniformity in specific forms of Islamic principles in Muslim countries. Certain Islamic banking procedures and financial instruments that are accepted in one Muslim country may be rejected in another 5 Muslim country.
