The Quran is complete and has no missing verses or chapters, as it has been perfectly preserved.

In the Islamic tradition, it is often asserted that the Quran has been perfectly preserved since its revelation. However, various Hadiths, such as those narrated by Anas bin Malik, suggest that there were verses that were once recited but later abrogated or cancelled. For instance, the narrations describe a specific verse concerning martyrs that was revealed but subsequently removed from the Quran. This indicates that there may be gaps in the Quranic text that are not acknowledged in mainstream Islamic belief. Moreover, the concept of abrogation (Naskh) in Islamic theology allows for the idea that some verses were meant to be temporary or context-specific. This raises further questions about the integrity of the Quran as a complete and unaltered text. If verses can be abrogated, it suggests that the Quran may not be the final, complete revelation as claimed. Additionally, the existence of narrations claiming that entire surahs are missing adds another layer of complexity to the assertion of the Quran's preservation. These reports challenge the notion that the Quran is wholly intact and have led some Christian apologists to argue that the Quran does not fulfill the criteria of a perfect scripture, as it is subject to changes and omissions over time.
