The Quran confirms the previous Scriptures and guards them in safety, which means that only the parts of the Bible that agree with the Quran are valid.

The Quranic verse Surah 5:48 states that it confirms the previous Scriptures and guards them in safety. This indicates that the Quran does not merely act as a criterion to judge the Bible but rather upholds its integrity. If the Quran genuinely protects the previous revelations, then the claim that the Bible has been corrupted cannot stand, as it would mean the Quran is inaccurate in its assertion. Furthermore, the Quran's role as a guardian implies that any teachings in the Bible that align with the Quran are valid and should be accepted by Muslims. Therefore, Muslims are compelled to acknowledge the authenticity of the Bible as a whole, rather than selectively accepting only those parts that coincide with Islamic teachings. This creates a significant challenge for the Muslim position, as it undermines the claim of corruption in the Scriptures.
