Forty Hadeeth Qudsi

الحديث القدسي هي الحديث الذي يعتبرون المسلمين كلام الله

Hadith Qudsi (or Sacred Hadith) is a sub-category of hadith which some Muslims regard as the words of Allah. According to as-Sayyid ash-Sharif al-Jurjani, the Hadith Qudsi differ from the Quran in that the former are "expressed in Muhammad's words", whereas the latter are the "direct words of God".

It is attributed to the Prophet Muhammad (peace be upon him), the Prophet of Islam because he is the one informing about Allah, which is contrary to the Quran which is attributed to no one except Allah.
