e9.0 Going to the lavatory
e9.4 It is obligatory to clean oneself of every impure substance coming from one's front or rear, though not from gas, dry worms or stones, or excrement without moisture.
e9.5 Stones suffice to clean oneself, though it is best to follow this by washing with water. Anything can take the place of stones that is a solid, pure, removes the filth, is not something that deserves respect or is worthy of veneration, nor something that is edible (O: these being five conditions for the validity of using stones (N: or something else) to clean oneself of filth without having to follow it by washing with water).
But it is obligatory to wash oneself with water if:
(1) one has washed away the filth with a liquid other than water, or with something impure;
(2) one has become soiled with filth from a separate source;
(3) one's waste has moved from where it exited (n: reaching another part of one's person) or has dried;
(4) or if feces spread beyond the inner buttocks (N: meaning that which is enfolded when standing), or urine moved beyond the head of the penis, though if they do not pass beyond them, stones suffice.
It is obligatory (N: when cleaning oneself with a dry substance alone) to both remove the filth, and to wipe three times, even when once is enough to clean it, doing this either with three pieces (lit. "stones") or three sides of one piece. If three times does not remove it, it is obligatory to (N: repeat it enough to) clean it away (O: as that is the point of cleaning oneself. Nawawi says in al-Majmu' that cleaning oneself (N: with a dry substance) means to remove the filth so that nothing remains but a trace that could not be removed unless one were to use water) (N: and when this has been done, any remaining effects of filth that could have been done, any remaining effects of filth that could have only been removed with water are excusable). An odd number of strokes is recommended. One should wipe from front to back on the right side with the first piece, similarly wipe the left with the second, and wipe both sides and the anus with the third. Each stroke must begin at a point on the skin that is free of impurity.
It is offensive to use the right hand to the oneself of filth.
e9.6 It is best to clean oneself of filth before ablution, though if one waits until after it to clean, the ablution is nevertheless valid(N: provided that while cleaning, the inside surface of the hand (def: e7.4 does not touch the front or rear private parts).
If one waits until after one's dry ablution (tayammum, def:e12) to clean away filth, the dry ablution is not valid (A: because lack of filth is a condition for it).
