Sahih Bukhari Volume 001, Book 005, Hadith Number 257.
Narated By Maimuna : I placed water for the bath of the Prophet. He washed his hands twice or thrice and then poured water on his left hand and washed his private parts. He rubbed his hands over the earth (and cleaned them), rinsed his mouth, washed his nose by putting water in it and blowing it out, washed his face and both forearms and then poured water over his body. Then he withdrew from that place and washed his feet.
