"Quranists" What do you know about the Prophet (saw) 's biography from Quran alone

I know what I need to know…That Prophet Muhammad was forbidden from teaching any other teachings other than the Quran alone. His biography (hadith & Sunnah) came AFTER he died. Thus, it is NOT from Muhammad. However, the Quran is 100% from Muhammad’s mouth, why don’t you follow that?!

Here is a wonderful video showing the history of hadith after Muhammad died.

Here is another video about your ‘authentic’ Sahih Hadithss and the blasphemies there.

I’m sure you will find an argument to support such nonsense.
