Unfortunately Islam does not have the same hierarchy like the Catholic church. Therefore religious reform would be quite difficult for them. And would need to be done almost on there government level. Since there religion and governments are almost one and the same its very easy for corruption to steer ether in the wrong direction. The arahamic religions have been at war with each other since there creations (Christianity , Judaism, Islam). The only difference now as to how they fight has only changed with technology.
