He, sallallaahu ‘alayhi wa sallam, instructed his wives to be devout worshippers:
Umm Salamah (the wife of the Prophet) narrated:
“One night the Messenger of Allah, sallallaahu ‘alayhi wa sallam, got up and said: “Glory be to Allah! How many afflictions Allah has descended tonight and how many treasures Allah has sent down [disclosed]! Who will go and wake the sleeping lady occupants of these dwellings [referring to his wives] up for prayers. A well-dressed [soul] in this world may be naked in the Hereafter.”
When Allah disclosed to the Messenger of Allah, sallallaahu ‘alayhi wasallam, the afflictions and treasures (rewards) that were sent down in one night, he, sallallaahu ‘alayhi wa sallam, got up in a state of astonishment and terror, because of the extent of good and evil that descended.
The Messenger of Allah, sallallaahu ‘alayhi wa sallam, was astonished at the fact that people were heedless of the extent of rewards and afflictions, because this should stimulate them to rejoice (for the reward) and fear the punishment awaiting those who commit the evil. This is why he, sallallaahu‘alayhi wa sallam, asked that his wives be woken up. This was an indication from him to his wives that they should not be heedless of performing acts of worship, and that they should not simply rely on the fact that they are the wives of the Prophet of Allah, sallallaahu ‘alayhi wa sallam. This narration encourages husbands to wake their wives up to pray at night, especially during the times when a celestial event is happening (i.e. like strong winds, hurricanes, tornadoes, eclipse and so on).
