Explanation of the words of Ibn Malik (may Allah have mercy on him): "And the hamzah of a word with a long vowel is reached in the genitive *** of what was in the dual for which it was derived."

The Shaykh :"And the hamzah of a word with a long vowel is reached in the genitive *** of what was in the dual for which it was derived"
Now we are going to look at how the short and long words are formed.
"And the hamzah of a word with a long vowel is reached in the genitive *** of what was in the dual for which it was derived"
The student: It is reached.

The Shaykh : Huh? How? It is reached, it is reached with an open vowel.
The student: It is reached.

The Shaykh : I am telling you it is reached.
"And the hamzah of a word with a long vowel is reached in the genitive *** of what was in the dual for which it was derived"
It means: that the long word is treated in the genitive as it is treated in the dual, and Ibn Malik says regarding the dual of long words
"And what is like a desert, dualize with a waw *** and the like of 'ilba', kisa', and haya
With a waw or a hamza, and other than what has been mentioned *** Correct it, and what is anomalous is shortened according to transmission.
So does that mean we must return to the dual?
The student: The long word.

The Shaykh : The dual of the long word "And what is like a desert" The alif in "desert" is a long vowel for the feminine, the marker of the feminine, the marker of the feminine. Ibn Malik says "dualize with a waw" So we say "deserts" (sahrawayn). The genitive is like the dual; we say regarding the genitive of "desert," "desert-like" (sahrawi) or "desert-like" (sahra'i)? "Desert-like" (sahrawi), because when "desert" is dualized, its hamzah must be changed to a waw, so when the genitive is formed from it, its hamzah must be changed to a waw. So we say for "desert," huh? "Desert-like" (sahrawi), right?
The student: Yes.

The Shaykh : Okay, "and the like of 'ilba', kisa', and haya
With a waw or a hamza
In "ilba," the hamzah is for addition. In "kisa," the hamzah is? It is original. The hamzah in it is original. So if the hamzah is for addition, like "ilba," or if the hamzah is original, like "kisa" and "ridda" and the like, then both options are permissible in it: keeping it as it is or changing it?
The student: A waw.

The Shaykh : To a waw. So we say for the genitive of "ilba"? A person who eats "ilba." Do you know what "ilba" is?
The student: ...

The Shaykh : "Ilba" is the tendons in the neck. A person who, praise be to Allah, has a strong stomach, you tell him to eat the tough meat. He does not say "ilba" is the tough tendons. So we say for the genitive of "ilba," we say this?
The student: Ilbawi.

The Shaykh : Ilbawi or?
The student: Ilba'i.

The Shaykh : Or Ilba'i. Both options are permissible. Okay, "kisa"? The hamzah is original. Is it permissible to say for the genitive of "kisa"?
The student: Kisa'i.

The Shaykh : Kisa'i and Kiswa'i, or not? Because the author says: "with a waw or a hamzah". Okay, "ridda"?
The student: Rida'i.

The Shaykh : Rida'i or Rida'i, "bina" (building)?
The student: Bina'i.

The Shaykh : Bina'i or Bina'i, and so on, apply this rule.
The student: "Himra" (red)?

The Shaykh : Huh?
The student: For the genitive of "Himra," we say "Himrawi"?

The Shaykh : And what did we say?
The student: ...

The Shaykh : ...
The student: Himrawi.

The Shaykh : Himrawi, "And what is like a desert, dualize with a waw"
"Sufra" (yellow)? Sufrawi. "Sawda" (black)? Sawdawi. As for "Sudani," that is the genitive of "Sudan," it is not the genitive of "Sawda." Okay, and what is not mentioned is correct. For example, "Qarra" (one who reads a lot) and "Dhidda" (one who performs ablution a lot). The hamzah here is original because it is from?
The student: "Qara" (to read).

The Shaykh : From "Qara" (to read) and "Tadha" (to perform ablution), so the hamzah is original. So we say for the genitive of "Qarra," huh? "Qarra'i." And for the genitive of "Dhidda"? Huh? "Dhidda'i." So is the meaning of these verses clear to us?
The student: Yes.

The Shaykh : So the genitive of what contains a hamzah is on three ways: either the hamzah is changed to a waw, or it remains as it is, or the person is given a choice between this and that. When is it changed to a waw?
The student: ...

The Shaykh : When it is for the feminine. And when does it remain as it is?
The student: When it is original.

The Shaykh : When it is original. And when is there a choice? When it is changed from its original form or when it is?
The student: For addition.

The Shaykh : For addition. Then both options are permissible in it, so you say for "ilba."
