While I would not call my self a distinct Quranist, (I simply has to little knowledge to choose either), I do think the Quranists has a good argument. The message given to Rasul Allah (صلى الله عليه وسلم وعائلته) is what is written in the Qur'an. And that must be the foremost authority to Muslims. The Hadith is hear say. As far as I understand the word "hadith" means something that people has said about the Prophet (صلى الله عليه وسلم وعائلته). That means that the hadith is not divine revelation
