Muslims regard the Hadith Qudsi as the words of God (Arabic: Allah), repeated by Muhammad and recorded on the condition of an isnad. According to as-Sayyid ash-Sharif al-Jurjani, the Hadith Qudsi differ from the Qur'an in that the former were revealed in a dream or through revelation and are "expressed in Muhammad's words", whereas the latter are the "direct words of God"..
This book will state some of the Qudsi Ahadith with spanish translation and then these ahadith will the explained in Spanish language.
