You obviously don't have a clue about the place of the Old Testament in Christianity and how it has been superseded by the teachings of Jesus.  At numerous points in the Gospels He instructs that the old teachings of the Law were wrong - e.g., not an eye for an eye, but love your neighbour.

His defiant insistence on such a definitive break from the old Law is one of the things that got him into such serious trouble with the Jewish leadership of the day.  Even His disciples were incredulous and had difficulty grasping how radically He was insisting on the new order as exemplified in the Beatitudes.

To try to equate the teachings of Jesus with those of Muhammad is ludicrous.
