Sayyiduna Abdullah bin Umar (may Allah be pleased with them) said: Sayyiduna Umar (may Allah be pleased with him) asked the Messenger of Allah (peace and blessings be upon him), "I become junub (in a state of major ritual impurity) at night?" The Prophet (peace and blessings be upon him) said: "Wash your private part, perform ablution, and go to sleep."

It is narrated from Abdur Rahman bin Aswad, his father asked Sayyida Aisha (may Allah be pleased with her) what the Messenger of Allah (peace and blessings be upon him) used to do if he wished to sleep in a state of major ritual impurity (janabah)? She replied: He would perform ablution (wudu) like that for prayer, and then he would sleep.
