And Abū Ishāq al-Isfarāyīnī (1) said:
“It is that which is commensurate with a given place and occupies a spatial location. To occupy a spatial location means that, if it is present in a void, it causes that void to cease being a void.”
Some of them said:
“A spatial location is the notional extent of a substance’s place.”
Abū al-Maʿālī al-Juwaynī—known as Imām al-Haramayn—said:
“A spatial location is none other than the entity occupying it; ascribing spatial location to a substance is like ascribing existence to it” (2).
He said:
“If it is objected, ‘Why, then, do you not say that an entity’s occupation of spatial location is due to an attribute, just as its being in a particular spatial state is due to an attribute?’
“We reply: ‘Its occupation of spatial location is identical with its essence—or is an essential attribute, according to those who affirm states. Its being an entity that occupies spatial location derives from its essence, as does its being a body. This does not vary, even though its spatial states vary through its accidents. If its occupation of spatial location were a property grounded in a cause, it would necessarily be subject to variation whenever its spatial states varied. Since its being a body does not vary, this shows that it is not a consequence of spatial states or of being assigned to particular directions. Whatever follows from spatial states is subject to variation.’”
