All of God's Prophets from Adam to Muhammad had the same message: Worship the Lord your God only and reject all false gods. It's that simple. The OT confirms this, Jesus Christ confirmed it and Muhammad confirmed and sealed it. All of your wishful thinking and pointless blather can't change that fact.I think it is also important to mention that when we consider the law of Moses including sacrifice. There were prophets after this who had a different message, but not one of them had a different law. The cohesion in regard to this subject is seen throughout the Bible with every prophet and fulfilled in Christ. This is another reason Muhammad is out on an island by himself that no prophet seen anywhere in scripture shares. All the prophets agree on the law. All the apostles agree on the fulfillment of the law through Christ. Muhammad removes the law as though the first five books of scripture were all corrupted and never applied the way they have been for thousands of years of recorded Jewish history beginning before Christ.
