The pharaoh's wife is not mentioned by name in the Quran but in the hadith....
Narrated Abu Musa Al Ashari
Allah's Apostle said, "Many amongst men attained
perfection but amongst women none attained the
perfection except Mary, the daughter of Imran and
Asiya, the wife of Pharaoh. And the superiority of
'Aisha to other women is like the superiority of Tharid
(i.e. an Arabic dish) to other meals."
[sahih bukhari]
