Professor Lumbard notes that the discovery of a Quranic text that may be confirmed by radiocarbon dating as having been written in the first decades of the Islamic era, while presenting a text substantially in conformity with that traditionally accepted, reinforces a growing academic consensus that many Western sceptical and 'revisionist' theories of Quranic origins are now untenable in the light of empirical findings – whereas, on the other hand, counterpart accounts of Quranic origins within classical Islamic traditions stand up well in the light of ongoing scientific discoveries.

Muslims believe that the present wording of the Quran corresponds to that revealed to Muhammad, and according to their interpretation of Quran 15:9, it is protected from corruption ("Indeed, it is We who sent down the Quran and indeed, We will be its guardian.").

Because the Quran is spoken in classical Arabic, many of the later converts to Islam (mostly non-Arabs) did not always understand the Quranic Arabic, they did not catch allusions that were clear to early Muslims fluent in Arabic and they were concerned with reconciling apparent conflict of themes in the Quran.
