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."
