أَخْبَرَنِي مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا مُحَمَّدٌ، - وَهُوَ ابْنُ ثَوْرٍ - عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ أَبِيهِ، قَالَ فِي حَدِيثِهِ إِذَا رَسُولٌ مِنَ النَّبِيِّ صلى الله عليه وسلم قَدْ أَتَانِي فَقَالَ اعْتَزِلِ امْرَأَتَكَ ‏.‏ فَقُلْتُ أُطَلِّقُهَا قَالَ لاَ وَلَكِنْ لاَ تَقْرَبْهَا ‏.‏ وَلَمْ يَذْكُرْ فِيهِ الْحَقِي بِأَهْلِكِ ‏.‏

It was narrated from 'Abdur-Rahman bin Ka'b bin Malik that his father said: "The envoy of the Messenger of Allah came to me and said: 'Keep away from your wife.' I said: 'Should I divorce her?' He said: 'No, but do not approach her.'" And he (the narrator) did not mention (the words): "Go to your family." Translation Not Available
