Marcion would agree with Muhammad about the true victim being not the Jewish Messiah:
And for their saying, “We have killed the Messiah, Jesus, the son of Mary, the Messenger of God.” In fact, they did not kill him, nor did they crucify him, but it appeared to them as if they did. Indeed, those who differ about him are in doubt about it. They have no knowledge of it, except the following of assumptions. Certainly, they did not kill him.

But, contra Muhammad, Marcion would have never adored who escaped the death under the traits of the Jewish Messiah.
This proves that Muhammad was a Judaizer, but differently from the Judaizers who judaized the true victim, Muhammad was a Judaizer who judaized the Jesus who escaped the death. Muhammad is not different in this from the inventors of Barabbas against Marcion. Only, with this difference:
- The inventors of Barabbas wanted to denigrate the false victim
- Muhammad wanted to adore the false victim.
