We must recognise - both Muslims and non- Muslims, that the Koran is a text. We need human engagement with that text, so we have to understand that the rulings and the legal rulings are produced are channelled through the human mind, it's an interpretive act of a human being engaging and interacting with a text producing legal results. Because of that it's susceptible to flaws, it is not perfect. Nobody has perfect access to the divine will.
