Refuting misconceptions:3-Authenticity and preservation of the Quran

[annatar]

what make you sure that he even said this?

so you are a sceptic now. but still you can easily accept that quran never changed although the fact that just few people knew by hearth the original quran at muhammed's time. Anyway every hadith i used is written by known scholars among muslims. Even muslims accept that they are true hadiths. btw you want me to search if its true. yet you use hadiths so easily in your arguments.
