[606] 57 - (262) It was narrated from 'Abdur-Raḥmān bin Yazīd, from Salmān that it was said to him: "Your Prophet has taught you everything, even how to defecate?" He said: "Yes. He forbade us to face towards the Qiblah when defecating or urinating, or to clean ourselves with our right hands, or to clean ourselves with less than three pebbles, or to clean ourselves with dung or bones."
