´It was narrated that Abu Hurairah said:` "The Messenger of Allah said: 'I am to you like a father to his son, and I teach you. So when you go to relieve yourselves, do not face the Qiblah or turn your backs towards it.' He ordered us to use three pebbles, and he forbade us to use dung and bones, and he forbade cleaning oneself with the right hand."

He said: "Yes indeed. He has ordered us not to face the Qiblah (prayer direction) nor to clean ourselves with our right hands, and not to be content with anything less than three stones, which are not to include any excrement or bones."
