Reading from Ibn Aqil’s commentary (may Allah have mercy on him), with the Shaykh’s annotations: " .

The reader: " And fa'lan as a noun, and fa'il, and fa'al *** other than one with a hamzah in the 'ayn, fa'lan encompasses:
From the patterns of plural of abundance, fa'lan, and it is analogical in a noun with a sound 'ayn on the pattern of fa'al, such as: dhahr and dhuhuran, and batn and batunan, or on the pattern of fa'il, such as: qadhib and qadhiban, and raghf and raghfhan, or on the pattern of fa'il " .

The Shaykh : Fa'il, raise the alif.
The reader: Fa'al.

The Shaykh : Fa'al, yes, without the example.
The reader: The verse breaks, O Shaykh.

The Shaykh : Huh?
The reader: The verse breaks.

The Shaykh : How?
The reader: It is the breaking of the letter before the last, and he said: fa'il, he said: fa'al at the end of the verse.

The Shaykh : Yes, correct, and fa'al encompasses, and fa'il and fa'al.
The reader: Shaykh.

The Shaykh : Yes, the verse does not break.
The reader: " Or on the pattern of fa'al, such as: dhakr and dhukhran, and haml and humlan " .

The Shaykh : Is that it? Qurs!
The reader: Qursan.

The Shaykh : Qursan or qarsan?
The reader: Qursan, qurs differs from this, this is fa'il.

The Shaykh : Yes, because what he brought is weak?! Yes.
The reader: This is: and not karim!

The Shaykh : And for karim.
The reader: This is the sin!

The Shaykh : It is not ...
The reader: And for karim.

The Shaykh : And for karim.
