Difference refers to its Maker and comparison refers to its comparer.
Difference refers to its Maker and comparison refers to its comparer. He, the Glorified, made them the evidences on His godhood and witnesses on His being not seen and speakers of His wisdom. The composition of these matters speaks of their being created. Their existence speaks of their nonexistence. Their movement speaks of their transience. Their expiry declares that their Creator will never expire.
This is Allah's saying: "And of everything we have created two pairs that you may be intelligent." He made difference between 'before' and 'after' so that it will be recognized that nothing was before Him and nothing will be after Him. The instincts of the creatures prove that their Maker has no instinct. The changeability of the creatures proves that the Maker of their changes is unchangeable. The timing of the creatures proves that the Maker of their timing is timeless.
He made screens among the creatures so that they will realize that there is no screen between them and Him. The confirmation of godhood had been proved to Him before the creation of the servants. The truth of lordship had been proved to Him before the existence of the slaves. The interpretation of hearing had been proved to Him before the existence of anything that is heard. The meaning of knowledge had been proved to Him before the existence of anything that is known.
The obligation of capability had been proved to Him before the existence of anything that is under capability. He deserved the name of 'the Creator' before He created the creatures, and deserved the name of 'the Maker' before He originated things. He distinguished the things without any means and collected them without any means. He arranged them without any efforts. Thoughts do not reach His essence and understandings do not comprehend His quintessence.
"When?" does not apply to Him, "may" does not make Him nearer, "probably" does not screen Him, "with" does not compare Him, and "He" does not comprise Him. Tools limit themselves only. Instrumentality refers to its likes. Deeds are found in the things themselves. Apparatuses tell of their neediness. Opposition tells of the opposite. Matches refer to their likes. Times refer to the events. Descriptions are distinguishable by the help of the names. The matches were discriminated from them.
Their events referred to them. "Since" prevented them from eternity. "May" stopped against their infinity. "Unless" denied its fatalism.
