Latin annotators charged the Qur’an with internal self-contradiction

Evidence

The theme of self-contradiction in the Qur’an can be illustrated over a wide field of examples. Some were noted in the margins of Ketton’s Qur’an: ‘A little before, he said that those who were rich in this world will be lost in the next; but now he says that Abraham was rich in this world and yet is to be numbered among the good.’ The Annotator apostrophised the Prophet, asking why there were these contradictions, and replying for him: sed ut mendax ubique tibimet ipst contrarius existis. — Norman Daniel, Islam and the West, 360
