Sunan an-Nasa'i, Book 27, Hadith 35 (In-Book) ⓘ
'Abdur-Rahman bin 'Abdullah bin Ka'b bin Malik narrated that his father said: "I heard my father Ka'b bin Malik -who was one of the three whose repentance was accepted- say: 'The Messenger of Allah sent word to me and to my two companions saying: The Messenger of Allah commands you to keep away from your wives. I said to his envoy: Shall I divorce my wife, or what should I do? He said: No, just keep away from her, and do not approach her. I said to my wife: Go to your family and stay with them. So she went to them.'"
أَخْبَرَنِي مُحَمَّدُ بْنُ جَبَلَةَ، وَمُحَمَّدُ بْنُ يَحْيَى بْنِ مُحَمَّدٍ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ مُوسَى بْنِ أَعْيَنَ، قَالَ حَدَّثَنَا أَبِي، عَنْ إِسْحَاقَ بْنِ رَاشِدٍ، عَنِ الزُّهْرِيِّ، أَخْبَرَنِي عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ كَعْبِ بْنِ مَالِكٍ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ أَبِي كَعْبَ بْنَ مَالِكٍ، - قَالَ وَهُوَ أَحَدُ الثَّلاَثَةِ الَّذِينَ تِيبَ عَلَيْهِمْ - يُحَدِّثُ قَالَ أَرْسَلَ إِلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم وَإِلَى صَاحِبَىَّ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم يَأْمُرُكُمْ أَنْ تَعْتَزِلُوا نِسَاءَكُمْ . فَقُلْتُ لِلرَّسُولِ أُطَلِّقُ امْرَأَتِي أَمْ مَاذَا أَفْعَلُ قَالَ لاَ بَلْ تَعْتَزِلُهَا فَلاَ تَقْرَبْهَا . فَقُلْتُ لاِمْرَأَتِي الْحَقِي بِأَهْلِكِ فَكُونِي فِيهِمْ فَلَحِقَتْ بِهِمْ .
