Issue 14...
Issue 14: When a source of impurity ['Aynun-Najaasah], like urine or blood, falls into Kurr water, the Kurr water does not become impure except when its color, taste or smell is changed by reason of this impurity. Issue 15: When we place something impure under flowing water from a pipe connected to a Kurr of water, then, the water which is separated from the impure thing is pure unless it had acquired the taste, color or smell of the impurity.
Issue 16: When we have doubt in water which was a Kurr or more than a Kurr as to whether it is now less than a Kurr or not, we apply the ruling of a Kurr upon it. Likewise, in the reverse, when we have doubt in water which was less than a Kurr as to whether it has now become a Kurr or not, we apply the ruling of a small quantity of water [Qaleel water] upon it.
Issue 17: Intended in (the term) small quantity of water [Maa’ul-Qaleel] is that which is less than the quantity of a Kurr and it does not come from within the earth. Issue 18: When an impurity comes into contact with a small quantity of water, all of the water becomes impure (based on obligatory precaution). Regarding when a small quantity of water is poured on to an impurity from above only the part of the small quantity of water contacting the impurity will become impure.
When, by means of a fountain, (the water) rises from the lower level to a higher level and the higher level makes contact with the impurity, the part contacting the impurity becomes impure not the lower part of the fountain.
Issue 19: When something Mutanajjis (contaminated with an impurity) is washed in a small quantity of water, it becomes pure (with the conditions which will be mentioned in that which follows) Issue 20: Flowing water is that water which springs from the earth (like the water of a stream or spring) or that which flows resulting from the continuous melting of ice gathered upon a mountain.
Issue 21: Flowing water does not become impure with contact with an impurity even though the flowing water is less than a Kurr, except when it acquired the taste, smell or color of the impurity. Issue 22: The water of pipes and, likewise, the water of the bathhouses connected to a storage tank, its ruling is the ruling of flowing water with a condition that the amount of water of the storage tank alone in addition to that which is in the pipes is not less than a Kurr.
Issue 23: The ruling of rain water is (same as) the ruling of flowing water.
