O Mufaddal, a time will come upon people the ignorant feels secure and the obscure fears, whose value is diminished among people, whom the affirmers envy and the opponents curse. This is near us and has a responder with us, and I will reveal that, O Mufaddal, so, listen to what is inspired to you and look with eye of your mind and listen with light of your intellect. Hear and perceive, for you asked about a great matter, a grave affair and a certain truth, and I shall cast upon you from it a heavy word and a majestic matter, and it is that which went astray in its knowledge many of creation and the vast multitude, save those your Lord spared. Indeed, He is the Forgiving, the Merciful.

It is what Al-Baqir informed Jabir son of Yazid Al-Ju’fi about when he had asked him about what you asked, and it is the greatest trial, the hidden secret, the difficult arduous knowledge and the rugged path, whose knowledge was hidden from all the worlds, except from the chosen specialists and the guarded eloquent ones, the sincere, the chosen, witnessing to what they knew, and believing in what they beheld, as the Revelation cites from the Majestic Master: Except who witnessed with the truth while they know.
