It is probably true that in every faith ordinary people will pick the parts they like best and practise those, while the scholars will work out an official version. In Islam the scholars had a particularly challenging task, given the mass of contradictory texts within the Koran.
To meet this challenge they developed the rule of abrogation, which states that wherever contradictions are found, the later-dated text abrogates the earlier one. To elucidate further the original intention of Mohammed, they referred to traditions (hadith) recording what he himself had said and done.
Sadly for the rest of the world, both these methods led Islam away from peace and towards war. For the peaceable verses of the Koran are almost all earlier, dating from Mohammed's time in Mecca, while those which advocate war and violence are almost all later, dating from after his flight to Medina.
