From Abu Huraira, who said: The Messenger of Allah (SAW) said: Truly I am to you all like a father to his son, I teach you all; whenever you go to defecate, do not face the qiblah and do not turn your backs to it. And He ordered them to use three stones, and forbade them to use dung or worn-out bones [or other decomposing body part; rimmah], and forbade anyone to wipe with their right hand.
