The Quran has remained unchanged and is the perfect word of Allah, unlike the Bible which has undergone many alterations.

The claim that the Quran has remained unchanged is challenged by various historical accounts that indicate alterations in its text. For instance, al-Bukhari narrates instances where companions of Muhammad reported different readings of verses, suggesting that the text was not uniformly preserved. These accounts highlight discrepancies in the recitation of key verses, such as the addition of clauses that were once part of the Quran but are now absent in the current version. This raises significant concerns regarding the claim of the Quran's perfect preservation. Moreover, the existence of multiple readings and interpretations of the Quran further complicates the assertion of its unaltered status. Scholars have documented variations in recitation and textual transmission that indicate a lack of uniformity. In contrast, the Bible, despite its translations, has a wealth of manuscript evidence that supports its textual integrity over centuries. The New Testament, for example, boasts thousands of manuscripts that allow for critical examination and reconstruction of the original texts. Ultimately, the argument for the Quran's unchanged nature does not hold up against the evidence of historical modifications and variations. This challenges the assertion of its divine preservation and invites a deeper examination of the reliability of both the Quran and the Bible in light of their respective historical contexts.
