Hadith Qudsi 40, Hadith Qudsi or Hadith Qudse (Arabic: الحديث القدسي‎, meaning "pure" or "holy Hadith") is a special category of Hadith, the compendium of sayings attributed to the Islamic prophet Muhammad. It is stated these Hadiths are unique because their content is attributed to God but the actual wording was credited to Muhammad.

Hadith Qudsi are direct revelation from Allah to the Prophet but conveyed to the people in the Prophet's own words and Hadith Nabawi are sayings or actions of the Prophet (p.b.u.h.) The chain of authority of Hadith Qudsi ends with Allah and that of Hadith Nabawi ends with the Prophet (p.b.u.h.)
