Juan Coles states:
Personally, I think it all came through Muhammad. Stylometric studies (Sadeghi) https://www.academia.edu/2572358/The_Chronology_of_the_Qur_ān_A_Stylometric_Research_Program do not find evidence of multiple authorship and I don’t see evidence of it myself. Compare the Hebrew Bible where the terms themselves demonstrate multiple authors. Likewise the epistles attributed to Paul. I do not believe that the Qur’an, which is a long literary document, is like the Safaitic inscriptions, which Sidky found also do not show multiple authorship even though there were lots of authors. But the inscriptions are short and very formulaic. Multiple authorship in the Qur’an should show up in the stylometry. It doesn’t. Further, since we now have van Putten’s study of quranic Arabic, it is clear that there are no texts in the Qur’an from outside the Hijaz, since they would be in a different dialect. This decisively disproves the Revisionist attempt to locate Islam’s origins in Jordan or Palestine.
- Marjin Van Putten’s view:
- He says that majority supports single authorship
- For his own view, his says that linguistically the Qu’ran is very consistent and obviously Hijazi Arabic. He said he disagrees that the Qu’ran is a collection of pieces from all over the ME or at least it must’ve been collected and translated at one point.
- This “translation” is not just replacing some words, it would affect the rhyme etc., so this would be a rather extensive reworking and recomposing to fit these texts into a new Hijazi Arabic linguistic form.
- Simply judging from its linguistic character, it seems perfectly consistent that the one who did that recomposition was a single person.
