The superiority of 'Aisha to other ladies is like the superiority of Tharid

Messenger of Allah (ﷺ) said, 

"The superiority of 'Aisha to other ladies is like the superiority of Tharid (i.e. meat and bread dish) to other meals. Many men reached the level of perfection, but no woman reached such a level except Mary, the daughter of Imran and Asia, the wife of Pharaoh." 

[Sahih al-Bukhari 3433]
