Explanation of the author's statement: For He, Glorified and Exalted is He, has no equal

The Shaykh : He says: "with the attributes of His creation, for He, Glorified and Exalted is He," this is the reasoning for the ruling. "They do not ask how or liken Him, for He, Glorified and Exalted is He, has no equal." Subhan: This is a noun of source (ism maddar) from the verb subha, and the source (maddar) from subha is tasbih; the source is tasbih. But Subhan means tasbih, indicating the meaning but not in the exact wording. Anything that indicates the meaning of a source without its exact wording is a noun of source, like Subhan, and for example Kalam (speech) instead of Taklim (speaking), and Tairah (omen) instead of Tatyur (taking an omen), and the like. Good.
Subhan is a noun of source from subha. So what is the meaning of subha? The scholars said its meaning is: to purify (tanzih). Its origin is from subh, which means distance. It is as if you distance the attributes of deficiency from Allah, Mighty and Majestic. So He, Glorified and Exalted is He, is purified from every deficiency. But what is its grammatical case? They say: It is always in the accusative case as an absolute object (maf'ul mutlaq), and its verb (amil) is always omitted. It is not possible for the verb to appear; that is, you cannot say "I say Subhan" (asbighu Subhan), but rather you say "Subhan," because it is more eloquent.
He says: "Glorified and Exalted is He, He has no equal, no peer, and no counterpart.": "He has no equal." The evidence for this is the saying of Allah the Exalted: Hal (Is there) is a question, but it means negation. Negation comes in the form of a question for a great benefit, which is the challenge (tahaddi). Because there is a difference between saying "He has no equal" or because contains both negation and challenge. So it is infused with the meaning of challenge. And this is a rule, understand it: "Whenever a question means negation, it is infused with the meaning of challenge." As if I am saying: If you are truthful, bring me an equal for Him. And on this basis, is more eloquent than: "He has no equal." Good.
