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."
