﴿ مِن فِرْعَوْنَ ۚ إِنَّهُۥ كَانَ عَالِيًۭا مِّنَ ٱلْمُسْرِفِينَ ﴾

“[inflicted on them] by Pharaoh, seeing that he was truly outstand­ing among those who waste their own selves;”

from Pharaoh min Fir‘awna is said to be a substitution for al-‘adhābi on the basis of an implied annexation that is to say min ‘adhābi Fir‘awna; or it is said to be a circumstantial qualifier referring to al-‘adhāb ‘the chastisement’. Truly he was a tyrant of the wanton ones.
