The Necessity of Hadith

Imagine a religion in which its adherents openly reject every saying, action, and event surrounding their Prophet &$. It is a Qur’anist’s reality. What exactly would lead to this stance, this scepticism, towards haduh? What would cause a Muslim to reject the teachings of the Prophet ¿E that he adores?! Everything about Islam is questionable without hadiths. What exactly do we know about the Prophet of Islam 2 without hadiths? Never mind his biography, we can’t even ascertain his identity. The Qur’än only identifies him as Muhammad (Q. 3:144). Couldn’t this be referring to Muhammad bin Maslama d. 43 AH) instead of Muhammad bin ’Abdilläh (d. 11 AH)? This book is directed to hadith-rejecters, to Muslims in general that are on the fence, as well as to conservative Muslims that seek to reaffirm their stance in regards to the authority of hadiths.
