Answer:
Jesus rose from the dead.
Step-by-step explanation:
Muslims believe that Jesus was a prophet from God, as well as Christians who also believe that he was the son of God, sent by God to save all humanity from its sins, but muslims do not believe that Christ rose from the dead, and the resurrection of Christ is the rock where the foundation of the Catholic church is found. So that is the thing that is not believed by muslims, but is believed by Christians, all the others are shared by both religions.
