If you say:

“What you have stated entails that every living being—or every human being—must have a god. But why could the soul not seek an object of worship in general, rather than a particular object of worship, and a kind of desired object, rather than a particular one?”

The answer is:

This is impossible. Something is sought either for its kind or for its particular identity. The former is exemplified by a thirsty person wanting water or a hungry person wanting food. Here, his desire is not directed towards any particular thing: whenever he obtains an instance of that kind, his purpose is fulfilled.

What is sought for its own sake, however, cannot be a kind, because one particular thing is not the other. If this one were sought for its own sake, it would follow that the other was not sought for its own sake. If what is sought for its own sake is what they have in common, it follows that whatever distinguishes one of them is not sought for its own sake. And if it is not sought for its own sake, it follows that whatever distinguishes each of them is not sought for its own sake.

A universal exists among concrete things only as something particular. Thus, if none of the particular things is sought for its own sake, nothing existing in external reality is sought for its own sake. There would therefore be nothing among them that anyone must worship, let alone something that everyone must worship.

It thus becomes clear that there must be a particular God whom every living being loves for His own sake. It is impossible for this to be anyone other than Allah; it must therefore be Allah. It is thereby known that, had there been gods besides Allah in the heavens and the earth, both would have fallen into ruin, and that every newborn is born loving this God, and love for Him
