Hadith
For most self-identified Muslims, hadiths are used along with the Qur'an to interpret Sharia. Sunnis follow the Kutub al-Sittah; Shias follow the Kutub al-Arba'a; Ibadis follow Tartib al-Musnad. Hadiths attributed to Abu Hurairah are the most common hadiths in Sunnism. Unlike the Qur'an, hadiths are not universally accepted by Muslims; some Muslims claim that most hadiths are fabrications (pseudepigrapha) created in the 8th and 9th century AD, and which are falsely attributed to Muhammad.
