This is the knowledge of the Truth through witnessing, direct vision, individualization (Tafrid), transcendence (Tanzih), and abstraction (Tajrid), just as we knew Him in this world esoterically and essentially. Thus, God Almighty said regarding those believers who knew Him with certainty (Tahqiq): {"...Whenever they are provided with a provision of fruit therefrom, they say, 'This is what we were provided with before...'"} (Al-Baqarah: 25). This is what they knew from the esoteric in this world, so they found it as a present reality before them in the Hereafter.. Therefore, the people of the known (Ma'ruf) in this world are the people of the known in the Hereafter.

The book (Clarification of Wills in the Forms of Acts of Worship) is a book containing Gnosis ('Irfan) and the elucidation of proof through conclusive evidence from the Quran, the Gospel, the Torah, the words of the Messengers and the infallible Imams—peace be upon them all—and from the books of the monotheists, may God sanctify them. It came about after written dialogues took place with some sheikhs who were establishing the exoteric law esoterically and professing it in seclusions at the expense of establishing the esoteric in seclusions. So the Beloved bound them with proofs and clarified the methodology for them, thus the right course and the core of the essence became evident.
