Narrated Abu Huraira:
The Prophet said, "Whoever believes in Allah and the Last Day should not hurt (trouble) his neighbor. And I advise you to take care of the women, for they are created from a rib and the most crooked portion of the rib is its upper part; if you try to straighten it, it will break, and if you leave it, it will remain crooked, so I urge you to take care of the women."
