Perhaps the āyah : “ Allah bears witness that there is no god but He, and (so do) the angels and the possessors of knowledge,” [^5] Is a hint at the Essence Testimony, for Allah, the Exalted, in the state of “the Collective Oneness” [ ahadiyyat-i dhātiyyah ] gives Personal testimony to His own Unity [ wahdāniyyat ], because mere existence by itself denotes the Essence-Oneness [ ahādiyyat-i dhātiyyah ], and in the rising of the Day of Resurrection it appears in Complete Unity [ wahdāniyyat - i tāmmah ].

This Oneness [ ahādiyyat ] appears first in the mirror of the Collectivity [ jam' ], then in the mirror of distinctness [ tafsīl ]. For this reason He said: “ …and the angels and the possessors of knowledge.” In this instance there are many states of knowledge [ ma'ārif ] that are out of the obligation of these pages to explain.
