The Quran is a complete and perfect record of what Muhammad transmitted to his followers.

The argument begins by citing various Islamic sources that confirm the existence of lost verses and surahs from the Quran. For instance, it is reported that Umar bin al-Khattab discovered that a specific verse was lost because the only person who had it was killed in battle. This indicates that not all revelations were preserved. Furthermore, reports from early Islamic scholars, such as Jalaluddin as-Suyuti, highlight that certain letters and verses were lost when companions of Muhammad died, particularly during battles like Yamama. Additionally, there are references to the verse of stoning, which was acknowledged by early leaders as having been revealed but subsequently lost. These historical accounts collectively support the claim that the Quran is not a complete record of Muhammad's teachings. The implications of these findings challenge the assertion of the Quran's perfection and completeness, suggesting that it is an incomplete compilation of revelations.
