—for by openly denying his own Prophet (1), Jesus, he is not allowed to remain on any creed other than Islam. He is summoned to repent; if he embraces Islam, all is well, but if he refuses he is put to death.

Section on Breach of the Covenant and Its Corollaries
Whoever breaks it—that is, the covenant—by contravening any of the conditions for which peace was granted, in any of the ways that will be detailed, forfeits both his property and his blood. This follows the wording of the letter from the inhabitants of al-Jazīra to ʿAbd al-Raḥmān ibn Ghannam: “If we change or oppose anything (2) we have stipulated upon ourselves and for which we accepted your guarantee of safety, then we have no pact of protection, and that which is permissible for you against the people of obstinacy and rebellion has become permissible against us.” ʿUmar ordered him to uphold that (3).
The annulment of the covenant does not depend on a judicial ruling by the ruler (4); once the covenant-breaker commits an act that nullifies it, the pact is void by that very fact, as is clear from what preceded.
