For this is a matter that is difficult, deemed demanding, and veiled in pearls; none bears it except a proximate angel, a sent prophet, or a believer whose heart Allah has tested for faith."

And he, glorified is his glory, was asked about the difficult and deemed demanding (al-sa'b al-mustas'ab)? So he said: "The difficult is the affirmation of the witnessed form, and the deemed demanding is the isolation of the Essence from the form."

And in another narration: "The difficult is the affirmation of the witnessed form, and the deemed demanding is the submission to it in servitude."

And the author of The Book of Al-Usayfir narrated: That our Master as-Sadiq, glorified is his glory, was asked about the difficult and deemed demanding? So he, glorified is his glory, said: "It is the recognition of the manifestation of the Divine within humanity."

Thus, not everyone who claims recognition is a gnostic, not everyone who claims monotheism is a monotheist, and not everyone who claims transcendence is a transcender.
