Explanation of the words of Ibn Malik (may Allah have mercy on him): "And delete it from the nominative of these two, and in *** the waw and ya, a matching form follows."

The Shaykh :"And delete it from the nominative of these two"
"And delete it from the nominative of these two" refers to? The waw and the ya. So, if a verb defective in alif is in the nominative, and it raises a waw or a ya, it is obligatory to delete it. And what is deleted?
The student: The alif.

The Shaykh : The alif, and for this reason he said "and delete it," meaning the alif.
"From the nominative of these two"
Which two?
The student: The waw and the ya.

The Shaykh : The waw and the ya, for example: "You will surely enter, O my people," "You will surely enter, O my people." Now, what is the nominative of the verb?
The student: Waw.

The Shaykh : The waw is the nominative. Where did the alif go? It was deleted and did not remain to be converted into a ya; rather, it is deleted. Allah the Exalted said: "You will surely see." The alif was deleted because the verb raised a waw. Now, if it raises a ya? The author says:
"And delete it from the nominative of these two" If it raises a ya, the alif is also deleted. The alif is deleted. Allah the Exalted said: The alif of the verb was deleted, and the existing ya is the subject. And likewise: The alif was deleted, and the existing waw?
The student: It is the subject.

The Shaykh : It is the subject. He said:
"And delete it from the nominative of these two, and in *** the waw and ya, a matching form follows"
Meaning: follow. And in the waw and ya that are in the nominative with a verb defective in alif, there is a matching form. "Qafi" means: follow. What matches the waw?
The student: The dammah.

The Shaykh : And the ya?
The student : The kasrah.

The Shaykh : The kasrah. And for this reason Allah the Exalted said: , and regarding the ya, He said: , Now, the summary: if the verb is defective in alif, and it raises a waw or a ya here? The alif is deleted. The alif is deleted, and the waw is marked with a dammah and the ya with a kasrah. And if it is raised by something other than the waw and the ya, then the alif is converted into a ya. The alif is converted into a ya, for example: "Zayd will surely run," "Zayd will surely run," or "You two will surely run," "You two will surely run." The alif was converted into a ya. Now, what about the verb defective in ya and waw? What do we do with the verb defective in waw and ya?
The student: It is deleted.

The Shaykh : It is deleted, as the author mentioned. Yes?
The student: ...

The Shaykh : Yes, he says:
"And delete it from the nominative of these two"
Yes, what is the example?
