The actual meaning of the verse is this: if someone heeds others who have not come to the Messenger, the Messenger is not obliged to judge between them. This includes a person under covenant—whether granted safe-conduct or otherwise—who refers matters back to his rulers and scholars in their own territory. It also includes a protected non-Muslim subject who accepts a judgment if it accords with his wishes, but otherwise returns to his leaders and scholars. Such a person chooses between obeying the judgment of Allah and His Messenger and turning away from it.
As for someone who submits only to the judgment of Allah and His Messenger and has no alternative to it—such as a wronged person seeking protection against his oppressor, with no one of his own religion to defend him—the verse grants no choice in such a case.
