Intertwined worlds: medieval Islam and Bible criticism
Contrary to the Christians, the Muslims did not consider the Bible as a holy text, therefore their polemics against the Jews took the form of Bible criticism. The main arguments used by Muslim thinkers against Judaism was that the Jews falsified God's word, or failed to transmit it properly, or misinterpreted the Bible, or that the Bible had been abrogated by God. The most prominent Muslim writers who developed these themes in the medieval period were Ibn Hazm and the Jewish apostate Samau'al al-Maghribi in the West of the Arab world, and Ibn Qayyim al-Djawziyya in the East. The first two considered, in particular, that it was Ezra ('Uzayr) who deliberately distorted the text of the Bible. Contends that the Muslim critics of the Bible based their arguments greatly on pre-Islamic sources (such as pagan, gnostic, Christian, and anti-Christian writings), and that they, in turn, were the source of early modern European Bible criticism.
