Don't urinate in holes or where there is wind

e9.1 It is recommended when one intends to use the lavatory:

(1) to put something on one's feet, unless there is an excuse (O:such as not having shoes);

(2) to cover the head (O:even if only with a handkerchief or other);

(3) to set aside anything on which there is the mention of Allah Most High. His messenger (Allah bless him and give him peace), or any revered name (O:like those of prophets or angels). If one enters with a ring (O:on which something worthy of respect is written), one closes one's hand around it;

(4) to ready stones (N: or other suitable material (def:e9.5)) (O:if one uses them) to clean oneself of filth (N:though water alone is sufficient);

(5) to say before entering: "In the name of Allah. O Allah, I take refuge in You from demons, male and female," and after leaving. 

"[O Lord,] Your forgiveness: Praise be to Allah who rid me of the hurt and gave me health";

(6) to enter with the left foot first and depart with the right foot first (and this, together with (3) and (5) above, are not only for indoors, but recommended outdoors as well);

(7) not to raise one's garment until one squats down to the ground (O: to keep one's nakedness covered as much as possible) and to lower it before one stand up;

(8) to put most of one's weight on the left foot while squatting;

(9) not to spend a long time;

(10) not to speak;

(11) when finished urinating, for men to squeeze the penis with the left hand from base to head (O: recommended because this is where the urethra is, and for women to squeeze their front between thumb and forefinger) (N: so urine does not exit later and nullify one's ablution) pulling lightly three times (O:this being recommended when one thinks the urine has stopped, though if one thinks it has not, this is obligatory);

(12) not to urinate while standing (O: which is offensive) unless there is an excuse (N: such as when standing is less likely to spatter urine on one's clothes than sitting, or when sitting is a hardship);

(13) not to clean oneself with water in the same place one relieved oneself, if it might spatter, though if in a lavatory one need not move to a different place;

(14) to distance oneself from others if outdoors and to screen oneself;

(15) not to urinate into holes, on hard places, where there is wind, in waterways, where people gather to talk, on paths, under fruit trees, near graves, in still water, or in less than 216 liters of running water;

(16) and not to relieve oneself with one's front or rear facing the sun, moon, or the Sacred Precinct in Jerusalem.

e9.2 It is unlawful to urinate on anything edible, bones, anything deserving respect, a grave or in a mosque, even if into a receptacle.

e9.3 It is unlawful to urinate or defecate with one's front or rear towards the direction of prayer when outdoors and there is no barrier to screen one, though this is permissible when one is indoors within a meter and a half of a barrier at least 32 cm. high, or in a hole that deep. When one is not this close to such a barrier at least 32 cm. high, or in a hole that deep. When one is not this close to such a barrier, it is not permissible except in a lavatory, where, if the walls are farther from one than the maximal distance or are shorter than the minimal height, relieving oneself with front or rear towards the direction of prayer is permissible, though offensive.
