It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: "I am like a father to you; when you go to relieve yourselves, do not face the Qiblah nor turn your back towards it." Then the Prophet, peace and blessings be upon him, forbade the use of dung and decayed bones (for cleaning after relieving oneself), and also said: "A person should not clean himself with his right hand."
