Narrated Anas:

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."

أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَنْبَأَنَا النَّضْرُ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ، عَنْ أَنَسٍ، قَالُوا يَا رَسُولَ اللَّهِ أَلاَ تَتَزَوَّجُ مِنْ نِسَاءِ الأَنْصَارِ قَالَ " إِنَّ فِيهِمْ لَغَيْرَةً شَدِيدَةً " .
