After composition, the compound substance (jawhar-i murakkab), and after the dissolution of the composition—that is, after its disintegration—it is called the simple substance (jawhar-i basīṭ) and the smallest indivisible part. For it is not correct to mention the part without considering the whole. The whole that remains after dissolution is the notional, dissolved compound body.
After knowing the substance (jawhar) in this way, you should know that accident (ʿaraḍ) consists of the state (ḥāl), attribute, condition, and properties of the substance. All these are the ever-changing accidents of the substance. For it is impossible for an accident to persist over two moments of time. The reason is this: the term accident is given because it transfers from one locus that accepts the accident to another. The substance, however, is the locus of the ferd (the indivisible unit); it does not accept the transfer of the accident to itself. On the contrary, the accident passes from it temporarily without uniting with it. This continues ceaselessly. (Marātib, 27)
One of the Marātib-i wujūd (levels of existence) is also the murakkabāt (composite entities). Composite beings are divided into six categories: compositions pertaining to knowledge, sight, hearing, body, spirit (rūḥ), and light (nūr). (Marātib, 28)
One of the Marātib-i wujūd is the falak-i atlas (the celestial sphere of Atlas). It revolves beneath the Kursī and above the other spheres, whose levels will be mentioned later. (Marātib)
