Is god confused?

One of the five doctrines of islam is that the koran is the final word of god and replaces all others.
Another doctrin of islam is that there have been many prophets sent by god. These prophets include Noah, Abraham, Moses, Jesus and mohammed. So what these two doctrines are saying is that the book which god spoke to, and is all about, these first four prophets Noah, Abraham, Moses, and Jesus was all wrong and the book which he finally gave to mohammed is the right one. Suddenly god realizes he has made a mistake and totally refutes what these first prophets have said and decides just the opposite is what he meant to say. Hate replaces love, fear replaces trust, despair replaces hope, death replaces life, sadness replaces joy, anger replaces peace, and shouting and vile epithets replace calm, reasoning communication. That is one screwed up confused god or the direct antithesis of God
