Much of the Quran has disappeared, and therefore, no one can claim to have the complete Quran.

The claim that much of the Quran is lost is supported by the narration of Abdullah ibn Umar, who stated that no one can claim to have the whole Quran because much of it has disappeared. This raises critical issues regarding the reliability and completeness of the Quran as a divine text. If significant portions of it are indeed lost, it challenges the notion of its divine preservation. Furthermore, the argument that lost verses have simply been abrogated does not resolve the issue; it instead suggests that a substantial part of the Quran's content is not applicable or relevant, which contradicts the idea of a consistent and eternal revelation. In contrast, the Christian doctrine holds that the Bible, as the inspired Word of God, is complete and has been preserved throughout history, providing believers with a reliable foundation for faith and practice.
