Quranism (Arabic: القرآنية, romanized: al-Qurʾāniyya; also known as Quranic Islam)[8][9] is a movement within Islam. It holds the belief that traditional religious clergy has corrupted religion, and Islamic guidance should be based strictly on the Quran, thus opposing the religious authority of all or most of the hadith literature.[10][11] Quranists believe that religious laws in the Quran are already clear and complete, and can be understood without referencing outside texts and extra non-Qur’anic sources.[12] Quranists claim that the vast majority of hadith literature are fabrications and that the Quran itself criticizes the hadith both in the technical sense and the general sense.[13][10][7][15][16][17] In the Muslim world, Quranists have faced opposition and have been labeled as "animals," and "apostates " in fatwas issued against them.
