And Muhammad ibn Rafi' narrated to us, from Abd al-Razzaq, from Ibn Jurayj, who said: Nafi' informed me, from Ibn Umar, that Umar asked the Prophet, peace and blessings be upon him, saying: "May one of us sleep while in a state of major ritual impurity (junub)?" He said: "Yes, let him perform ablution (wudu'), then sleep, until he bathes (ghusl) whenever he wishes."
