'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.'"
