According to them, a hadith narration about history can be true or can be false, but a hadith narration adding rulings to religion is always completely false.[68] They believe that the trustworthiness of the narrator is not enough to give credibility to hadith, as, they state, it is stated in the Quran that Muhammad himself couldn't recognize who was real believer and who were hypocrite in their mind.[69] Moreover, Quranists quote Sahih Muslim 42:7147 to argue Muhammad forbid any hadith beside the Quran.[70]
