The Holy Bible has been corrupted and no longer represents the original teachings of God's messengers, which is why the Quran was sent as a criterion to judge it.

The assertion that the Bible has been corrupted is challenged by the overwhelming evidence of manuscript copies, with nearly 25,000 fragments and whole texts dating back centuries before the Quran. Textual critics, including non-Christians, have determined that the variants found in these manuscripts do not affect any major doctrines, as they are primarily minor discrepancies. Additionally, the Quran acknowledges the Torah and the Gospel that were in existence during Muhammad's time, indicating that these texts were recognized as the Word of God. Verses from the Quran, such as Sura 7:156-157 and Sura 5:46, highlight that the Gospel referred to is singular and aligns with the four Gospels of the New Testament, further supporting the claim that the Bible has not been corrupted.
