Allah Most High says:

“Indeed, this is Our provision, which will never run out.”
Sād: 54.

He thus declares that the kind is never exhausted, while each of its individual portions is exhausted.

Time and the motions of bodies are described as long and extended, but no small part of them is described as long and extended. Thus, saying that the Lord has always possessed things whenever He wills, or has always done whatever He Himself wills—in the sense that He has always spoken and acted, and that His speech and actions endure perpetually—does not entail that each individual act has existed perpetually without beginning.

If you say:

“A temporal occurrence, precisely insofar as it is a temporal occurrence, must be preceded by something else, just as a contingent being, precisely insofar as it is contingent, must depend upon something else, and a thing brought into being, precisely insofar as it is brought into being, must need something else. Just as contingent beings, individually and collectively, must depend upon an agent, as must things brought into being, so too temporal occurrences, individually and collectively, must be preceded by something else.”

This is akin to their statement:

“Motion, precisely insofar as it is motion, must be preceded by something else, because its parts are successive rather than simultaneous.”

Your opponents reply: “This is an ambiguous and equivocal expression.”

For the most part, your false arguments and those of others rest upon ambiguous, equivocal expressions, while disregarding relevant distinctions. They take an ambiguous, equivocal expression without distinguishing one of its two meanings from the other. Through equivocation and confusion in words and meanings, many people have gone astray.
