Some Muslims believe that the Torah has been corrupted (tahrif). The exact nature of the corruption has been discussed among scholars. The majority of Muslim scholars including Ibn Rabban and Ibn Qutayba have stated that the Torah had been distorted in its interpretation rather than in its text. The scholar Tabari considered the corruption to be caused by distortion of the meaning and interpretation of the Torah. Tabari considered the learned rabbis of producing writings alongside the Torah, which were based on their own interpretations of the text. The rabbis then reportedly twisted their tongues and made them appear as though they were from the Torah. In doing so, Al-Tabari concludes that they added to the Torah what was not originally part of it and these writings were used to denounce the prophet Muhammad and his followers. Tabari also states that these writings of the rabbis were mistaken by some Jews to be part of the Torah. A minority view held among scholars such as Al-Maqdisi is that the text of the Torah itself was corrupted. Maqdisi claimed that the Torah had been distorted in the time of Moses, by the seventy elders when they came down from Mount Sinai. Maqdisi states that the Torah was further corrupted in the time of Ezra, when his disciples made additions and subtractions in the text narrated by Ezra. Maqdisi also stated that discrepancies between the Jewish Torah, the Samaritan Torah and the Greek Septuagint pointed to the fact that the Torah was corrupted. Ibn Hazm viewed the Torah of his era as a forgery and considered various verses as contradicting other parts of the Torah and the Qur'an. Ibn Hazm considered Ezra as the forger of the Torah, who dictated the Torah from his memory and made significant changes to the text. Ibn Hazm accepted some verses which, he stated, foretold the arrival of Muhammad.
