Not at all, the Koran is written in the context of Arabia at the time. This is not a matter of interpretation, the book itself references local customs and laws. Therefore, our understanding, the practice and everything else in Islam is crucially shaped by the society in Arabia, and the change it brought to it. I think it is best read and understood in terms of the Delta - the change - it meant to convey (but that is my opinion). On the other hand, however, much of the Arabic language and customs are of course shaped by Islam. For example, one difficulty of interpreting the Islam is that the words that are used now convey the connotation that was coined by centuries of religious practice, and it is difficult to know exactly what they originally meant. In addition, much like the Bible (translations), it coined many terms and semantic concepts. Overall, the question you pose it not answerable in any way. Interpreting the core - the Koran - does not have a unique solution. And even though Islam has taken great care to preserve the text, traditions and reasons behind them, it is not clear cut. For example, the large majority of Muslisms prescribe to the Hadiths as interpretation and additional norms, but there are also Hadidths stating that you should not do that, and the Koran is enough. But on that basis, many more interpretations would be possible. Paradoxically - and in contrast to Christianity - the Muslisms who rely primarily on the book alone, are much more progressive than the ones also relying on the traditions. I don't think your question will find a true answer.
