Ruling 26
Qalīl water with which the urinary outlet or the anus are washed does not make anything it comes into contact with impure, provided that five conditions are met:
1. it does not acquire the smell, colour, or taste of the impurity;
2. another impurity has not come into contact with it;
3. another impurity, such as blood, has not come out with the urine or faeces;
4. particles of faeces do not appear in the water;
5. a more than usual amount of impurity has not spread around the urinary outlet or the anus.
-Ayatullah Sistani, Practical Laws of Islam, Purification (Taharah)
