The excellence of performing Wudu' before sleep

Q: Is someone who is Junub (in a state of major ritual impurity) allowed to sleep without performing Wudu’ (ablution)?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions.There is no sin if one who is Junub sleeps in this state without performing Wudu’. Yet, it is preferable to perform Wudu’ before going to bed because the Prophet (peace be upon him) did that and commanded to do so.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
