Al-Rāzī (2) and al-Āmidī (3) answered them by denying that necessity is a positive attribute, along with other responses of this kind that we endorse.

It would then follow that (5) the Necessary Existent is composed of that by which it shares in common and that by which it is distinguished. It would also follow that necessary existence is an effect.
The same counterargument may be made in terms of reality: reality is divided into necessary and possible, and the necessary is distinguished from the possible by what is particular to it. It would therefore follow that necessary reality is composed of what is shared and what is particular, and that necessary reality is an effect. The counterargument may likewise be framed in terms of quiddity, for it is divided into necessary and possible, and so forth.
Second: resolving the specious argument. Two things existing (6) in external reality—whether both are necessary or possible, and whether the division is posited between two existents, two substances, two bodies, two animals, two human beings, or anything else—do not share
