سُبْحَانَ ٱللَّٰهِ

According to almost all of the commentators, this parenthetic passage (verses {23-24}) is primarily addressed to the Prophet, who, on being asked by some of the pagan Quraysh as to what "really" happened to the Men of the Cave, is said to have replied, "I shall give you my answer tomorrow" - whereupon revelation was temporarily withheld from him in token of God's disapproval; in the second instance, this exhortation expresses a general principle addressed to all believers.
Verses 23 and 24 are parenthetical. We must never rely upon our own resources so much as to forget Allah. If by any chance we do forget, we must come back to Him and keep Him in remembrance, as did the Companions of the Cave.
In geometry the perfect circle is an ideal. Any given circle that we draw is not so perfect that we cannot draw one closer to the ideal. So in our life, there is always the hope of drawing closer and closer to Allah.
