That is another thing. I do not deny that problem but those conflicts were not for material gains. In godless society model the war is on from inter county level to inter country level. In business big fish eat small fish on regular basis even with following the rules the society has defined.
I found 12 different definitions of riba a few years ago when I was looking for one.
Most “divine” laws have varying definitions and are open to interpretation. We can see such contrasting ways to interpret religion if we compare societies in Saudi Arabia and Iran and Egypt.
As is said those are applied to themselves. If you are looking for confusion you will find one for sure. As for as I know fixed interest is considered haram in every sect. The willingness of enforcement varies from sect to sect, however. fixed interest based saving account is haram. no sect would allow it. but again the problem is willingness. Moderates would not want to implement it to remove these type of transactions from financial organizations. Now if you start with removing this type of transaction you will be able to move further easily. The moderate Muslims believe riba in some other form is allowed have not yet come up with established solution. Just excuses.
