Sahih Muslim Book - 17, Hadith - 3644

وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِى شَيْبَةَ حَدَّثَنَا حُسَيْنُ بْنُ عَلِىٍّ عَنْ زَائِدَةَ عَنْ مَيْسَرَةَ عَنْ أَبِى حَازِمٍ عَنْ أَبِى هُرَيْرَةَ عَنِ النَّبِىِّ -صلى الله عليه وسلم- قَالَ « مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَإِذَا شَهِدَ أَمْرًا فَلْيَتَكَلَّمْ بِخَيْرٍ أَوْ لِيَسْكُتْ وَاسْتَوْصُوا بِالنِّسَاءِ فَإِنَّ الْمَرْأَةَ خُلِقَتْ مِنْ ضِلَعٍ وَإِنَّ أَعْوَجَ شَىْءٍ فِى الضِّلَعِ أَعْلاَهُ إِنْ ذَهَبْتَ تُقِيمُهُ كَسَرْتَهُ وَإِنْ تَرَكْتَهُ لَمْ يَزَلْ أَعْوَجَ اسْتَوْصُوا بِالنِّسَاءِ خَيْرًا ».

It was narrated from Abu Hurairah that the Prophet (s.a.w) said: "Whoever believes in Allah and the Last Day, if he witnesses something let him speak good or else keep silent. Deal kindly with women, for woman was created from a rib, and the most crooked part of a rib is its upper part. If you try to straighten it you will break it, and if you leave it alone it will remain crooked. Deal (kindly) with women."
