The Quran is the perfect and unaltered word of God, unlike the Bible which has many textual variants.

The argument begins by acknowledging that both the Quran and the Bible have textual variants, which raises questions about their respective claims to divine preservation. Notably, scholars, including Muslim translators, have admitted to the existence of variants within the Quran, suggesting that it is not immune to the same issues that Muslims often attribute to the Bible. Furthermore, the Quran itself acknowledges the Bible as a source of divine revelation, which complicates the Muslim claim of the Quran's superiority. If the Bible is deemed flawed based on textual variants, then the Quran, which references the Bible, must also be scrutinized under the same criteria. This creates a logical inconsistency in the Muslim argument that the Quran is the unaltered word of God.
