Sunnah
Literature on Muhammad's deeds and sayings
Sunnah is the body of traditions and practices of the Islamic prophet Muhammad that constitute a model for Muslims to follow. For Muslims, the sunnah is what all the Muslims of Muhammad's time supposedly saw, followed, and passed on to the next generations. However, what constitutes the Sunnah, and its interpretation, depends significantly on the specific Islamic sect and school of thought. Sunnis rely on six major canonical hadith collections to document the Sunnah, known as Kutub al-Sittah. For Shias, the sunnah is generally documented in Kutub al-'Arba'a, which give preference to hadiths attributed to the Prophet's family and the Twelve Imams. For Ibadis, the sunnah is documented in the two hadith collections Jami Sahih and Tartib al-Musnad. Sufis hold that Muhammad transmitted his sunnah, including his spiritual values, "through a series of Sufi teachers".
