People of Pharaoh or Family of Fir’awn?

Did the author of the Quran think that Fir’awn (Pharaoh) was a proper name? In a number of passages we come across al Fir’awn, but we also come across al Ibrahim and al Imran and al Ya’qub, which are unquestionably the family of Ibrahim, the family of Imran and the family of Ya’qub respectively.

S 3:33 Allah chose Adam and Nuh and Ibrahim’s family and Imran’s family over the ‘alamin.

S 4:54 Or do they envy people for what Allah has given them from his favour? But we gave Ibrahim’s family the Book and the Wisdom and we gave them a great dominion.

S 12:6 And thus does your lord choose you and teach you of the interpretation of the ahadith and complete his grace upon you and upon Ya’qub’s family as he completed it upon your two fathers before, Ibrahim and Ishaq. Your lord is learned, wise.

So it seems likely that when the author said al Fir’awn he meant the family of Fir’awn. In S 7:109 we find qawm Fir’awn. Qawm does mean ‘people’.

The chiefs of Fir’awn’s people said: This is a learned magician.

Let the reader decide.
