It is narrated about Sayyiduna Salman al-Farsi (may Allah be pleased with him): A polytheist mocked him and said, "I have noticed that your master has taught you everything, even the manners of relieving yourselves." Sayyiduna Salman (may Allah be pleased with him) replied, "Yes! The Messenger of Allah has instructed us that when we perform istinja (cleaning after relieving oneself), we should neither face nor turn our backs to the Qiblah, nor use the right hand for istinja, nor use less than three stones, and none of those stones should be a bone or dung."
