Explanation of the words of Ibn Malik (may Allah have mercy on him): "And its deletion for the jussive and the accusative is its sign *** a word that you might say to a wronged woman."

The Shaykh : The author said: "And its deletion for the jussive and the accusative is its sign". "Sign" means a marker. So if you put one of the five verbs in the accusative, delete the noon; and if you put it in the jussive, delete the noon.
Allah the Exalted said: The first is in the jussive, and the second is in the accusative. All right.
If you said, "The men did not stand up" (al-rijalu lam yaqumun), that is incorrect. Why? Because it is in the jussive, so the noon must be deleted.
"The two men did not stand up" (al-rijalana lam yaqumana) is incorrect. The noon must be deleted.
"You two will not spare any effort" (antumata lan ta'lawani jahda) is incorrect. The correct form is "You two will not spare any effort" (lan ta'lawani jahda).
"And its deletion for the jussive and the accusative is its sign *** a word that you might say to a wronged woman"
"You will not be" (lam takuni) is originally "you will not be" (lam takunina). The noon was deleted because of the jussive particle "lam."
And his saying: "to a wronged woman" is in the accusative because of the lam of negation. The lam of negation is the lam of denial, meaning negation. So "to a wronged woman" is in the accusative because of the lam, and the sign of its accusative is the deletion of the noon. The "ya" is the subject.
And "wronged woman" is the object. All right, pay attention. The five verbs, also called the five examples. O Adam, O Zakariyya, what are they?
The student: ... .

The Shaykh : Correct. All right, how do you parse them?
The student: They are parsed as nominative with the noon present.

The Shaykh : Yes.
The student: And as accusative and jussive with the noon deleted.

The Shaykh : With the noon deleted. All right. For the five verbs, it is permissible to say: they are "they do" (yaf'alan), "you two do" (taf'alan), "they do" (yaf'alun), "you all do" (taf'alun), and "you do" (taf'alin). It is also permissible to say: every present-tense verb to which is attached the alif of the dual, the waw of the plural, or the ya of address. If you said, "every present-tense verb to which is attached the alif of the dual, the waw of the plural, or the ya of address," that is correct. And if you said, "they do, you two do, they do, you all do, and you do," that is also correct. All right.
Is the verse following this parsing? What put it in the jussive? Not the prohibitive "la," but what put it in the jussive? The sign of the jussive is the deletion of the noon. The sign of the jussive is the deletion of the noon. The apparent meaning of the author's words is that the noon is not deleted except in the state of jussive or accusative. But that is not his intention. Rather, his intention is that if it is put in the accusative, the noon must be deleted, and if it is put in the jussive, the noon must be deleted. The noon may be deleted for other reasons. The noon may be deleted for reasons other than the jussive; it is deleted for ease, as in his saying, peace and blessings be upon him and his family: "You will not enter Paradise." What is the original form? "You will not enter" (la tadkhulun). This is the obligatory form, because "you enter" (tadkhulu) is now in the nominative, since "la" here is a negator. "Until you believe" (hatta tu'minu). Ah, on the original form, why? It is in the accusative with the noon deleted. On the original form, "you do not believe" (la tu'minun). On the original form.
The student: No.

The Shaykh : It is not on the original form, because here it is in the nominative and the noon was deleted. On the original form, but this is for ease. Likewise, it is deleted with the noon of protection, with the noon of protection, permissibly as well. So you might say, for example, "Do you honor us" (atukramuni) instead of "Do you honor us" (atukramunni). The original form is "Do you honor us" (atukramunni), but the noon is also deleted with the noon of protection for ease and to avoid the succession of two extra noons. All right.
And it is deleted obligatorily with the noon of emphasis. The noon is deleted obligatorily with the noon of emphasis, such as "you will surely stand" (li-taqumanna). Its original form is "you will surely stand" (li-taqumunna). It is deleted with the noon of emphasis obligatorily. Why? Because of the succession of similar letters. Because of the succession of similar letters.
So it is deleted obligatorily when a marker of accusative or jussive enters it, and with the noon of emphasis. And it may be deleted for ease in other states, in the state of nominative, for reasons other than these two. All right.
I hope you pay attention to the summary: The five verbs are "they do" (yaf'alan), "you two do" (taf'alan), "they do" (yaf'alun), "you all do" (taf'alun), and "you do" (taf'alin). And we can express it with another expression. Come on, Zaki.
The student: ... .

The Shaykh : Yes, perfect. Their ruling is that they are in the nominative with the noon present, and in the accusative and jussive with the noon deleted. So it is easy and simple.
