Explanation of the Author's Statement: His saying (… the destructive sins. They said: O Messenger of Allah, what are they? He said: Associating partners with Allah)

The Shaykh : And his saying: The destructive sins, meaning the things that lead to destruction. Allah the Exalted said: Mubiq means destructive, meaning a place of destruction.
And his saying:
In this, there is first a general statement, then a detailed one. So what is the benefit of the general statement first?
The benefit is to arouse the listener’s desire for the explanation of this general statement, because if a thing is explained from the very beginning, it does not receive the same attention and acceptance as when it is first mentioned generally and then explained, or not? Therefore, when people are told that something important is coming, they pay more attention to it than if you simply said such and such happened, or not? You find them eager to know what this important thing is. So when he said:
Ma: An interrogative noun, acting as the subject (mubtada').
Wa-hunna: The predicate (khabar) of the subject. Hunna is the predicate of the subject, yes.
And some grammarians said: It is the opposite. Hunna: A postponed subject, and Ma: A fronted predicate, obligatory, or is it permissible? Obligatory, why? Because it is an interrogative, and since it is an interrogative, it takes precedence. Those who chose that said: Because hunna is a definite pronoun and ma is an indefinite noun, and the known rule is that the predicate is an indefinite noun referring to a definite subject, not the other way around. So they consider this structure to be a fronted predicate, and hunna: a postponed subject. And it is possible to say: That hunna is a pronoun referring back to ma, which is an indefinite noun, and the pronoun referring to an indefinite noun is indefinite. So although it is a pronoun, it has the meaning of an indefinite noun because it refers to an indefinite noun. As they said regarding the phrase: "Rabbi huwa rajulun salih" (My Lord, he is a righteous man), where they introduced Rabbi to the pronoun, even though it is not introduced to anything but an indefinite noun.
Ibn Malik said:
"And specify with miz and minz a time *** And with Rabbi an indefinite noun"
And despite that, it was introduced to the pronoun because it has the meaning of an indefinite noun.
And he placed it first because it is the greatest of the destructive sins, for the greatest of sins is to make a rival for Allah, while He is your Creator. Associating partners with Allah includes associating partners with Him in His Lordship, or His Divinity, or His Names and Attributes. So this is the greatest of the destructive sins: associating partners with Allah. Whoever believes that there is a Creator with Allah is an associate of partners with Allah. Or whoever believes that there is one with Allah who is independent in creating some things is an associate of partners with Allah. Or whoever believes that Allah has a helper who helps Him is also an associate of partners with Allah. And whoever believes that anyone other than Allah deserves to be worshipped is an associate of partners with Allah, whether he worships him or not, as long as he believes that someone deserves to be worshipped alongside Allah, he is an associate of partners with Allah, even if he does not worship him. If he worships him, it is even greater. If he worships him, it is even greater. Likewise, whoever believes that Allah has a like in His attributes is an associate of partners with Allah. Whoever believes that Allah rose above the Throne as a king rises above the throne of his kingdom is an associate of partners with Allah. And whoever believes that Allah descends to the lowest heaven as a person descends from the top of his house to the bottom is an associate of partners with Allah. So the important point is that associating partners with Allah is one of the destructive sins, and it is the greatest and most severe of these destructive sins. And the Messenger (peace and blessings be upon him) clarified that this is among the greatest of crimes and sins. He said: He who created you, brought you into existence, provided for you, prepared you, and sustained you, how can you make a rival for Him? If someone were to do you a favor less than that, and you made a rival for him, what would this matter be in relation to him? Is it disbelief and denial, or not? It would be disbelief and denial, and it is not appropriate. He does you good and you do him wrong; this is never appropriate.
