It was narrated from Anas that they said: "O Messenger of Allah, why don't you marry a woman from the Ansar?" He said: "They are very jealous." (Using translation from Nasāʾī 3233)  

عَنْ أَنَسِ بْنِ مَالِكٍ قَالُوا يَا رَسُولَ اللهِ أَلَا تَتَزَوَّجُ مِنْ نِسَاءِ الْأَنْصَارِ؟ قَالَ «إِنَّ فِيهِمْ لَغَيْرَةً شَدِيدَةً»
