(483) بَابُ أَكْلِ الرَّجُلِ مَعَ امْرَأَتِهِ
'A'isha said, "I used to eat date and butter mixture with theProphet, may Allah bless him and grant him peace. 'Umar visited and theProphet invited him and he ate. 'Umar's hand touched my fingers and hesaid, 'Oh! If I were to be obeyed about you, no eye would ever see you!'Then the veil was revealed."
