Ḥadīth (حديث‎ ḥadīth, pl. Aḥādīth, أحاديث, ʼaḥādīth, also "Traditions") in Islam are the record of the words, actions, and silent approval, traditionally attributed to the Islamic prophet Muhammad. Within Islam the authority of hadith as a source for religious law and moral guidance ranks second only to that of the Quran.
