Islamic tradition implies that God expunged Uzayr as a prophets because he refused to believe in qadar, but Ibn Hazm, al-Samaw'al and other scholars vocalized that Uzair falsified the Torah (the first five books (Pentateuch or five books of Moses) of the Hebrew Bible).
However, Islamic tradition also reports that God expunged Uzayr from the list of prophets because he refused to believe in qadar (predestination). Ibn Hazm, al-Samaw'al and other scholars put forth the view that Uzair (or one of his disciples) falsified the Torah, and this claim became a common theme in Islamic polemics against the Bible. It can most specifically mean the first five books (Pentateuch or five books of Moses) of the Hebrew Bible.
