Re: why people have started rejecting ahadees these days
There were hadees books written by Sahabas also such as Saad ibn Abi Waqas and many more. There were many hadees books written during the times of sahabas and also by tabieen. Even if Quran was compiled before, there were only few copies of it, it was transmitted through oraly. Same way hadees were transmitted this way.
So you didnt answer, how you know this is the Quran that was revealed to Prophet s.a.w.
