The Prophet (ﷺ) was keen to teach his nation all aspects of Islam and correct the mistakes and habits they followed during the period before Islam. Thus, he taught them the etiquette of relieving oneself. The polytheists used to mock his companions and wondered, as Salman narrated, that the Prophet (ﷺ) taught his companions all Islamic matters even if how they should purify themselves after answering the call of nature. As a result, Salman proudly answered them, "Yes" and added that the Prophet (ﷺ) taught them to avoid the right hand in purifying oneself from urine or feces, due to respecting and dedicating it to honorable and noble things while dedicating the left one to remove filths and impurities. Purification is to use water or something similar to remove what comes out from one's penis, vagina, or anus. Salman added that the Prophet (ﷺ) prohibited them from facing the prayer direction while answering the call of nature. This is applied to doing so in deserts not in houses or similar close places. Abu Daoud reported that Marwan ibn Al-Asfar narrated, "I saw Ibn Omar when he making his camel kneel and facing the prayer direction. He sat down to urinate, so I asked him, "O Abu Abdurrahman, was it not forbidden?" He replied, "It is only forbidden if you do it in deserts, but there is no problem if there is something between you and the prayer direction." Salman added that the Prophet (ﷺ) and prohibited them from using dung or bones in purification. The former material is impure and the latter is the food of jinn. In Sahih Muslim, the Prophet (ﷺ) answered the Jinn when they asked him for food, "Every bone on which the name of Allah is recited is your provision. When it falls in your hand, it will be completely covered with flesh, and every dung is fodder for your animals." Salman added that the Prophet (ﷺ) prohibited them from purifying themselves (after answering the call of nature) with less than three pure and dry pebbles. A Muslim can use more than three pebbles until he makes sure he is completely purified. Finally, this hadith contains the following benefits: (1) It clarifies the Prophet's keenness to guide his nation to all useful points, even the most minute details, (2) It contains some of the etiquette that a Muslim has to follow while relieving himself, and (3) A Muslim has to be proud of Islamic teachings, especially in front of those mocking and ridiculing him..
