Musnad Ahmad 1153:2365

'Amir ibn Salih narrated to us, he said: Hisham ibn 'Urwah narrated to me, from his father, from 'Aishah, that the Messenger of Allah, peace and blessings of Allah be upon him, said: "The woman is like a rib; if you straighten her, you will break her, and she is enjoyed while there is crookedness in her."
