....It is not necessary to wipe one's anus with three stones or with three pieces of fabric: a single stone or single piece of fabric is enough. But if one wipes with a bone, or any sacred object, such as, for example, a paper having the name of
Allah on it, one may not say his prayers while in this state.
...During evacuation, one must not squat facing the sun or the moon, unless one's genitals are covered. While defecating, one must also avoid squatting exposed to the wind, or in public places, or at the door of one's house, or under a
fruit tree. At the time of the evacuation, one must also avoid eating, dallying, or washing one's anus with the right hand. Finally, one must avoid talking, unless one is absolutely forced to or is addressing a prayer to
Allah.
....Urinating and defecating are forbidden in four places: blind alleys, except with the permission of those living along them; the property of a person who has not given permission to do so; places of worship, such as a certain
medersas [Arabic schools]; graves of believers, unless one does so as an insult to them.
