Explanation of the words of Ibn Malik (may Allah have mercy on him): "Following the yaa of diminutive, before a proper noun *** femininity or its elongation, the fathah is necessitated."

The Shaykh : Then it said:
"For the yaa of the diminutive, before a proper noun *** of femininity or its elongation, the fathah is necessitated"
The issue before us is what comes after the yaa of the diminutive, after the yaa of the diminutive: is it with a fathah or with a kasrah?
The student: It is with a kasr.

The Shaykh : Huh?
The student: It is with a kasr.

The Shaykh : It is with a kasrah, fu'ay'il, fu'ay'il, but the author says:
"For the yaa of the diminutive, before a proper noun *** of femininity"
If the yaa of the diminutive comes in a feminine proper noun, then what comes after the yaa of the diminutive is not made with a kasrah; rather, it is made with a fathah. What is an example?
The student: 'Abid.

The Shaykh : Huh?
The student: 'Abidah.

The Shaykh : 'Abidah?
The student: 'Abilah, 'Abilah.

The Shaykh : No, that is the alif.
The student: Fatimah, Futaymah.

The Shaykh : Do we say for Fatimah: Futaymah, or not?
The student: Yes.

The Shaykh : And we do not say Futaymah on the pattern of fu'ay'il, no, we say Futaymah. Wardah? The student: Wuraidah.

The Shaykh : Wuraidah, and for this reason he said: "the fathah is necessitated" Likewise, he says: "or its elongation" What is the elongation? The elongation of the taa of femininity, whether it is elongated or short. So we say for Salma: Sulayma, and we do not say: Sulimi, rather we say: Sulayma. And we say for Sahraa? Here?
The student: Suhayraa.

The Shaykh : Suhayraa, and for this reason he said: "or its elongation, the fathah is necessitated"
