1. "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."
[Sahih al-Bukhari 3331]
2. "Woman has been created from a rib and will in no way be straightened for you; so if you wish to benefit by her, benefit by her while crookedness remains in her. And if you attempt to straighten her, you will break her, and breaking her is divorcing her."
[Sahih Muslim 1467 b]
