Sahih Bukhari Volume 001, Book 005, Hadith Number 266.
Narated By Maimuna bint Al-Harith : I placed water for the bath of Allah's Apostle and put a screen. He poured water over his hands, and washed them once or twice. (The subnarrator added that he did not remember if she had said thrice or not). Then he poured water with his right hand over his left one and washed his private parts. He rubbed his hand over the earth or the wall and washed it. He rinsed his mouth and washed his nose by putting water in it and blowing it out. He washed his face, forearms and head. He poured water over his body and then withdrew from that place and washed his feet. I presented him a piece of cloth (towel) and he pointed with his hand (that he does not want it) and did not take it.
