Volume 4, Book 55, Number 548:
Narrated Abu Huraira:

Allah 's Apostle said, "Treat women nicely, for a women is created from a rib, and the most curved portion of the rib is its upper portion, so, if you should try to straighten it, it will break, but if you leave it as it is, it will remain crooked. So treat women nicely."

^ Bukhari under 'Prophets'


Book 008, Number 3466:
AbuHuraira (Allah be pleased with him) reported Allah's Messenger (may peace be upon him) as saying: Woman is like a rib. When you attempt to straighten it, you would break it. And if you leave her alone you would benefit by her, and crookedness will remain in her. A hadith like this is reported by another chain of narrators
