I was in the company of Messenger of Allah ﷺ 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).
أَنَّهُ كَانَ مَعَ رَسُولِ اللَّهِ ﷺ فِي سَفَرٍ وَأَنَّهُ ذَهَبَ لِحَاجَةٍ لَهُ وَأَنَّ مُغِيرَةَ جَعَلَ يَصُبُّ الْمَاءَ عَلَيْهِ وَهُوَ يَتَوَضَّأُ فَغَسَلَ وَجْهَهُ وَيَدَيْهِ وَمَسَحَ بِرَأْسِهِ وَمَسَحَ عَلَى الْخُفَّيْنِ
