Pastor Troy. The Quran is an all in 1 . It contains all the relevant prophets. None of which ever did anything bad. You will not find a single prophet that slept with his daughters, or got drunk, or behaved indecent. The prophets were the perfect role models in the Quran. Just as you would expect anyone you look up to or was sent by God to act like. So no we do not need the bible or the torah to understand the true message of the oneness of God as promoted and spoken of sinceAbraham .
