Explanation of the saying of Ibn Malik (may Allah have mercy on him): "And in the passive participle of the trilateral, the pattern of maf'ul is consistent, like 'at' from qasd."

The Shaykh :"And in the passive participle of the trilateral, the pattern of maf'ul is consistent, like 'at' from qasd"
This is after the passive participle of the trilateral verb, which is consistent in the pattern of maf'ul. The passive participle of the trilateral is on the pattern of maf'ul. Ah, you say: "dhubba" so it is "madhruub," "ukila" so it is "ma'kul," "ukhrija"?
The student: "Makhruj."

The Shaykh : "Makhruj," why?
The student: This is a quadrilateral.

The Shaykh : This is a quadrilateral, correct. "Kharaja"?
The student: "Makhruj."

The Shaykh : Huh?
The student: "Makhruj, makhruj."

The Shaykh : How? "Makhruj."
The student: This is a trilateral.

The Shaykh : No, "makhruj" is from "akhraja."
The student: ... .

The Shaykh : No, the correct answer is that you did not say "makhruj." You say: "This door is makhruj minhu" (this door is exited from), this door is makhruj minhu, it is consistent. But "makhruj" is from the transitive verb, whereas "kharaja" is intransitive. This is what made you say "makhruj." We say: No, we keep "makhruj" but we make it transitive to an object with a preposition, so we say: "makhruj minhu." Okay, "dakhala al-bayt" is "madkhul" ah, or not? Okay, so the author (may Allah have mercy on him) says: The rule in the passive participle:
"And in the passive participle of the trilateral, the pattern of maf'ul is consistent, like 'at' from qasd"
"At" means: like the passive participle that comes from "qasd."
The student: "Like the passive participle that comes from qasd".

The Shaykh : How? "Qasada" so it is "maqsud." Now let's look, let's return to the parsing of the verses. We are not going to parse them, nor do you remember the parsing.
The student: ... .

The Shaykh : Ah, correct... and it is carried over to what the language brought.
