Explanation of the author's (may Allah have mercy on him) statement: " . . .

The Shaykh : He said: So the inflected words "So that which is inflected by vowel movements is of four types: the singular noun, the broken plural, the sound feminine plural, and the present tense verb to which nothing is attached at its end" We add "to which nothing is attached at its end," and it is not built, and it is not built. Okay, the ones inflected by vowel movements, these are types... And the evidence is tracking and induction, for we tracked the speech of the Arabs and did not find in their speech anything that is inflected by vowel movements, yes, by vowel movements, except these four types. Okay, he says: "And all of them are raised with a dammah, accusative with a fathah, genitive with a kasrah, and jussive with a sukun" Jussive with a sukun, all of them, here, how?
The student: Error

The Shaykh : No.
The student: Are all of them jussive with a sukun?

The Shaykh : No, he says: "All of them are raised with a dammah, accusative with a fathah, genitive with a kasrah, and jussive with a sukun"

The Shaykh : It is not all of them.

The Shaykh : It is subtle, all of this is a rule, this is a rule, but he says: "And three things are excluded from this" meaning he made exceptions, and what I said is not correct, it is not all of them like this, and therefore he made exceptions. He said: "And three things are excluded from this: the sound feminine plural is accusative with a kasrah" From where is this excluded? From his statement: "And accusative with a fathah" So what is excluded from that?
The student: The sound feminine plural.

The Shaykh : The sound feminine plural, this is not accusative with a fathah, it is accusative with a kasrah. And the noun that does not decline is genitive with a fathah, this is derived from his statement: "And genitive with a kasrah" meaning except the noun that does not decline. "And the present tense verb" is the third, "with a defective final letter" is jussive by deleting its final letter, correct. So the rule now, with the exception, is sound, with the exception. Once again, I return to the fact that what is inflected by vowel movements is four things: the singular noun.
And the second: the broken plural.
And the third: the sound feminine plural.
And the fourth: the present tense verb to which nothing is attached at its end, and it is not built. Clear. Okay, although our saying "and it is not built" here, we might do without it, because the built form must have something attached to its end, a nun of emphasis or a nun of women. Okay, pay attention, these inflected by vowel movements, their rule is that they are raised, the rule in them is raised with a dammah, accusative with a fathah, genitive with a kasrah, jussive with a sukun. But three things are excluded from this. First: the sound feminine plural is excluded in one state, it is not accusative with a fathah, but rather accusative with a kasrah, and it is raised.
The student: With a dammah.

The Shaykh : According to the original rule, and it is genitive with a kasrah according to the original rule, and it is jussive with a sukun according to the original rule.
The student: It is not jussive.

The Shaykh : Why? It is a noun, there is no jussive in it.
The student: This is the secret of the jussive...

The Shaykh : What, what? Okay, but the author made an exception here.
The student: ... .

The Shaykh : Why?
The student: Because he did not exclude the jussive.

The Shaykh : Yes, based on the fact that he said previously: "So for nouns, of that, there is raising, accusative, and genitive, and there is no jussive in them" Based on what came before...
Okay, so the present tense verb with a defective final letter is jussive, and what remains for us is the noun that does not decline, which is genitive with a fathah. Okay, it is raised.
The student: With a dammah.

The Shaykh : And it is accusative.
The student: With a fathah.

The Shaykh : It is accusative.
The student: With a fathah.

The Shaykh : The noun that does not decline is accusative with a fathah, yes, it is genitive.
The student: With a fathah.

The Shaykh : With a fathah. So it is excluded from our saying "and genitive with a kasrah." It is excluded that the noun that does not decline is genitive with a fathah, except when it is made definite or preceded by al. Okay, good.
The author said: "And the present tense verb" This is also an exception from his statement: jussive with a sukun. The present tense verb is jussive by deleting its final letter. The one with a defective final letter is jussive by deleting its final letter, and it is raised.
The student: With a dammah.

The Shaykh : And it is accusative.
The student: With a fathah.

The Shaykh : And it is genitive.
The student: It is not genitive.

The Shaykh : It is not genitive, yes, because the genitive is one of the markers of a noun. Okay.
So if we asked a questioner: With what is the present tense verb raised? The answer would be.
The student: With the damma.

The Shaykh : And with what is it accusative?
The student: With a fathah.

The Shaykh : And with what is it jussive? With a sukun, except if it has a defective final letter, then it is jussive by deleting its final letter. With what is the singular noun raised?
The student: With the damma.

The Shaykh : And it is accusative.
The student: With a fathah.

The Shaykh : And it is genitive.
The student: With a kasrah.

The Shaykh : And it is excluded from that the one that does not decline, which is genitive with a fathah, broken with a fathah. Okay, with what is the sound feminine plural raised?
The student: With the damma.

The Shaykh : And it is accusative.
The student: With a kasrah.

The Shaykh : And it is genitive with a kasrah. Complete. Okay.
