The Qu’ran says God is not three in one, that Jesus Christ is just a messenger of Allah. Muhammad is the last messenger. The Bible says God is three in one, that Christ is the living son of God. He’s the first and the last.

Buddhism denies the concept of a God; that there are no moral absolutes in life, only guidelines. And, the Bahais say Muhammad, Jesus, Siddharta are all manifestations of God on earth to spread peace and love.
