Narrated Um Salama:
(One night) the Prophet () woke up and said, "Subhan Allah ! How many treasures have been (disclosed) sent down! And how many afflictions have been descended! Who will go and wake the sleeping ladyoccupants up of these dwellings (for praying)?" (He meant by this his wives.) The Prophet () added, "A well-dressed soul (person) in this world may be naked in the "Hereafter." `Umar said, "I asked the Prophet, 'Have you divorced your wives?' He said, 'No.' I said, 'Allahu Akbar.' "
