What did the Prophet Muhammad (saw) do after he answered the call of nature when he was on a journey?
 Narrated Al-Mughira bin Shu`ba:                     I was in the company of Allah's Apostle on one of the journeys and he went out to answer the call of nature (and after he finished) I poured water and he performed ablution; he washed his face, forearms and passed his wet hand over his head and over the two Khuff (socks made from thick fabric or leather).
