Musnad Ahmad 30:3318

'Abd al-Malik ibn 'Abd al-Rahman al-Dhamari narrated to us, Sufyan informed us, from Abu al-Zinad, from al-A'raj, from Abu Hurayrah, that the Prophet, peace and blessings of Allah be upon him, said: "Indeed, women were created from a rib; they will not be upright for you upon one way. If you seek to straighten her, you will break her; and if you leave her, you will enjoy her while there is crookedness in her."
