Is this rule correct: If an attribute of Allah appears in the Qur'an in the plural form, we do not take from it the affirmation of the attribute?

Question:
May Allah reward you. Honorable Shaykh, this questioner says: Is this statement correct? It states that if [a word] is in the plural form, it is an attribute of Allah (Mighty and Majestic), and it is an attribute of Allah (Mighty and Majestic), and it is an attribute of the Qur'an in the plural form, so we do not take from it the affirmation of the attribute. But if it comes in the singular or dual form, we take from it the affirmation of the attribute, as Allah the Exalted said:

Answer:
I have told you how many times: do not set up rules from your own minds. Go back to the words of the Salaf in this matter and the guidelines followed by the righteous Salaf.
My brother, if an attribute is added to a singular noun, it is made singular, and if it is added to a plural noun, it is made plural, for the sake of linguistic correspondence. So one does not say "our hand," but rather "our hands," a correspondence in wording. The word "na" (our) regarding Allah is a pronoun of majesty, not a pronoun of the plural. Rather, it is the pronoun of majesty. This is even according to the scholars of grammar, who say that when "na" is intended to refer to the singular, it is for majesty. And is there anyone greater than Allah (Glorified and Exalted is He)?
It is a pronoun of majesty, and the hands were made plural, "our hands," relative to the pronoun because it is in the form of the plural, so the hands were made plural for correspondence. And I advise you not to speak about these matters without insight and without knowledge, or to set up rules from your own minds. Yes.
