Musnad Ahmad 788:184

Yahya ibn Sa'id and Muhammad ibn Ja'far narrated to us, they said: Shu'bah narrated to us. Yahya said in his narration: 'Amr ibn Murrah narrated to me. Ibn Ja'far said: From Murrah al-Hamadani, from Abu Musa al-Ash'ari, from the Prophet, peace and blessings of Allah be upon him, who said: "Many men have attained perfection, but no women have attained perfection except Maryam bint 'Imran and Asiya, the wife of Pharaoh. And the superiority of 'Aisha over women is like the superiority of Tharid over all other food."
