Sahih al-Bukhari, Hadith 5184 ⓘ
Narrated Abu Huraira: Allah's Messenger said, "The woman is like a rib; if you try to straighten her, she will break. So if you want to get benefit from her, do so while she still has some crookedness."
حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " الْمَرْأَةُ كَالضِّلَعِ، إِنْ أَقَمْتَهَا كَسَرْتَهَا، وَإِنِ اسْتَمْتَعْتَ بِهَا اسْتَمْتَعْتَ بِهَا وَفِيهَا عِوَجٌ " .
