The closest and most viable cause must relate to "jizya", that is, unlawfully consuming what belongs to the Muslim state, which, al-Bayḍāwī explains, "it has been decided that they should give," since their own scriptures and prophets forbid breaking agreements and not paying what is due to others. His Messenger in this verse has been interpreted by exegetes as referring to Muḥammad or the People of the Book's own earlier messengers, Moses or Jesus. According to Abdel-Haleem, the latter must be the correct interpretation as it is already assumed that the People of the Book did not believe in Muḥammad or forbid what he forbade, so that they are condemned for not obeying their own prophet, who told them to honour their agreements.
