Narrated Khuzaymah ibn Thabit: The Prophet ﷺ was asked about cleansing (after relieving oneself). He said: (One should cleanse oneself) with three stones which should be free from dung. Abu Dawud said: A similar tradition has been narrated by Abu Usamah and Ibn Numair from Hisham.
The Prophet's answer also shows us how important it is to pay attention to details when performing religious duties such as cleansing ourselves after relieving ourselves. We must take care not only to use something pure but also something appropriate for the task at hand - in this case, three stones instead of paper or cloth - so as not to miss out on any blessings or rewards associated with performing these acts correctly according to Islamic teachings.
