What I understand: 1) The basis of truth in Islam, is the Quran. 2) Its truth can confirmed by nature of man agreeing with it. So would you say, man would naturally agree with the Quran. (I'll have to go back and read it with this in mind) However it appears the nature man does not necessarily agree with the interpretation of the Quran. As is evident with the various sects of Islam, although agreeing with the Quran, seem to disagree with its understanding. If true... How do you determine what is true from among the different sects? Who is right?
