Criticism of ḥadīth is the critique of ḥadīth—the genre of canonized Islamic literature made up of reports of the words, actions, and the silent approval of the Islamic prophet Muhammad. The legitimacy of ḥadīth is of considerable importance in mainstream Islam because of Quranic injunctions for Muslims to obey Muhammad (in verses such as 24:54, 3:32), and that "he is an excellent example for anyone who has hope in Allah and the last day" (33:21). Mainstream Islam holds that the Sunnah—teachings and doings of Muhammad—are like the Quran, divine revelation to be obeyed, but the "great bulk" of the rules of Sharia (Islamic law) are derived from ḥadīth rather than the Quran.
