Ḥadīth in Islam refers to the record of the words, actions, and the silent approval, of the Islamic prophet Muhammad. Within Islam the authority of Ḥadīth as a source for religious law and moral guidance ranks second only to that of the Qur’an (which Muslims hold to be the word of Allah revealed to his messenger Muhammad). Quranic verses (such as 24:54, 33:21) enjoin Muslims to emulate Muhammad and obey his judgements, providing scriptural authority for ahadith. While the number of verses pertaining to law in the Quran is relatively few, ahadith give direction on everything from details of religious obligations (such as Ghusl or Wudu, ablutions for salat prayer), to the correct forms of salutations and the importance of benevolence to slaves. Thus the “great bulk” of the rules of Sharia (Islamic law) are derived from ahadith, rather than the Qur’an.
