Not really how it works.
Surah are chapters in the Quran.
Chapters in the Quran are made up of verses (ayat, s. ayah) that are considered to be the words of God.
Being together in one Surah doesn't mean that the verses were recited at the same instance;
it groups them together in a unit for reciting, but there might be years between the reveal of one verse and another.
Surah are well known and undebatable; they are extremely well known and make up the core of the Islamic corpus
The problem with the Quran, is that it doesn't contain crucial info, like how to pray, how to pay taxes and which hand you should wipe your ass with.
The grand majority of all Islamic law is based on hadith, which are thousands of fragmentary reports on things the prophet said or did.
A hadith takes the form of a matn and an isnad.
The former is the content of the text, the latter is a chain of narrators like "Umar told me, Zaid told, Ahmed told, Abu Hurairah told, the prophet said"
The problem, already noted by the end of the first century of Islam, is that most of these hadith are fake.
That's were the hadith verification system comes in.
There are thousands of hadith, and most of them are very obscure; most well-known hadith are from the "six authentic books" of which only Sahih Muslim and Sahih al-Bukhari are considered mostly reliable.
Even then, most of these "sahih" or "sound" hadith don't stand up to historical scrutiny, because the hadith verification method has some problems.
Point is, nobody but scholars knew this hadith,
it's probably not sahih,
and if it was, scholars would have probably deboonked it in one way or another.
