Musnad Abu Ya'la al-Mawsili 243:48

Mujahid ibn Musa narrated to us, Abu Usamah narrated to us, Shu'bah narrated to us, from 'Amr ibn Murrah al-Hamdani, from Murrah, from Abu Musa al-Ash'ari, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Many men have attained perfection, but no women have attained perfection except Maryam bint 'Imran and Asiyah, the wife of Pharaoh. And the superiority of 'Aishah over women is like the superiority of Tharid over all other food."
