Ka'b bin Malik narrated the Hadith about when he stayed behind, and did not join the Messenger of Allah on the expedition to Tabuk. He told the story, and said:
The envoy of the Messenger of Allah came to me and said: 'The Messenger of Allah commands you to stay away from your wife.' I said: 'Shall I divorce her or what?' 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 until Allah, the Mighty and Sublime, decides concerning this matter.'
