The confusion arises when Quran is treated as the Book of a religion while it challenges all the religions like Judaism , Christianity ,idol-worship , star-worship ,nature-worship & all kinds of superstitions & declares all of them as based on false foundations. This might be a surprise to non-Muslims but to Muslims as well. Madhhab & Din are erroneously treated as synonymous while both are different concepts & are mutually contradictory.The clash of interests among various groups of mankind can only be eliminated through a Divine Guidance from a source ie supra-human .Man is not merely a physical being but is composed of Nafs (Individuality/I-amness in an undeveloped form & the development of personality is the major aim of a man in this world which can only grow in a society under the umbrella of Quran in the shape of a concrete system & not in isolation .Thus all of us who are leading our lives under a non-Quranic Govts are declared by Quran as Kafiroon/Zalimoon/Fasiqoon. I don't find a single ayah which supports to be qualified for Jannah being conditions of human life & not places or localities ; the same is true for jahannam while in isolation . .We all should convey the Quran & try our level best to adhere to its teachings .Islam does not exist in the entire social life of mankind .We all are believers of Illah-us-sama & rejectors of Illah-ul-arz. The law of requital is very scientific , anyone with more than 50% marks will be qualified for eternal life of Jannah subject to leading life under Quranocracy while less than 50 % will enter into jahannam like a seed which is permanently decayed if not nurtured properly.
Only Saliheen (The fittest ) will qualify provided they led their lives under a collective Quranic social Order (As-salat ) & Quranic system of sustenance or Rabubiyyah (Az-zakat ).
Allah even cries over such devastation of mankind "Ya hasratan alalibad " O my Ibad ! what have you done with yourselves (individualities ). Even Allah never interfers in this scientific law of requital .
Let us propagate Quran ; probably that is the only way which might open the door of our success .
