It is narrated from Sayyiduna Salman al-Farsi (may Allah be pleased with him) that a polytheist mockingly said: "I see that your Prophet even teaches you the manners of relieving yourselves." Sayyiduna Salman (may Allah be pleased with him) replied: "Yes, absolutely," he (peace and blessings be upon him) commanded us that "we should not face the Qiblah nor turn our backs towards it (while relieving ourselves), nor use the right hand for cleaning, nor suffice with less than three stones, and none of them should be dung, manure, or a bone."
