Interesting answer. I am only questioning/learning about the order of surah not the contents.
Quran was revealed over several years. Part by part.
First Iyat is not the first in the Quran as it is present today.
Not possible to have Quran recited in SAME order BEFORE it was compiled by Hazrat Umer (RAA) or even Hazrat Abu Bakar (RAA).
Even during the days of Hazrat Abu Bakar (RA) Surahs were not in order. Verses were rememberd as in succession and continuous chain. And each Surah was written separately.
When Zayd Ibne Taabith was asked to write down an authentic Quran from his and other people’s memory, different items where it was written, he asked why do U want to do it when the prophet (SAW) himself did not do.
Well the discussion will go too far if we keep going.
All I wanted to mention that recitation of Surah in order is good as they are but it could not have been done prior to its compilation.
Even people from different areas were reciting differently and hence Huzayfa Ibne Yamaan had to go to Umer (RAA) to make one authentic copy to be distributed to various places.
( 5 or 7 copies were then made one was kept in Medina)
