" In „The Secret of Secrets“, al-Jilani refers to the Hadith Qudsi, where God speaks through His Messenger, peace be upon him:

„Man is My secret and I am his secret. The inner knowledge of the spiritual essence (ilm al-batin) is a secret of My secrets. Only I put this into the heart of My good servant, and none may know his state other than Me.“ (p. 192) "
