In technical terms...

In technical terms, composite making ( ja‘l ta’līfī ) and independent creation do not apply to them, even if the mind is able to consider them as independent whatnesses. Considering this point, there is a sense in which they can be taken to be accidents of bodies, but accidents whose existence is the very existence of the body, and all of their whatnesses exist by one existence. In other words, the existence of these kinds of accidents is an aspect of the existence of substances.

Relational Categories Among the ten categories, there are seven each of which is regarded as possessing some kind of relation, and for this reason they are called the ‘relational categories,’ and some philosophers have taken them to be species of the category of relation ( nisbah or iḍāfah ).

The relational categories are as follows: The category of relation ( iḍāfah ), which is obtained from the occurrence of a relation between two existents, and is divided into those which have similar terms, and those which have opposite terms. The former kind is like the relation ‘being the brother of’ which holds between two brothers, or the relation of simultaneity between two things which exist at one time.

The latter kind is like the relation of a father to his child, or the relation of priority and posteriority between two parts of time, or two phenomena which come into existence at two times. The category of where ( ‘ayn ), which is obtained from the relation between a material thing and its location. The category of when ( matā ), which is obtained from the relation between a material existent and its time.

The category of position ( waḍ‘ ), which is obtained from the relation among the parts of a thing to each other, considering their directions, such as the condition of standing, a posture in which the parts of the body are located over one another so that the head is on top, or the condition of reclining, which is abstracted from the location of the parts of the body next to one another in a horizontal form.

The category of possession ( jidah or milk ), which is obtained from the relation of one thing to another which more or less encompasses it, like the condition of the body being covered by its clothes, or the head being covered by a hat. The category of activity ( an yaf’al ), which describes the gradual influence of a material agent on the matter acted upon, such as the sun which gradually warms water.
