The book of purification;
Water
Purifying water is the only purifying liquid among liquids. Purifying water is that water which can be termed water without a necessary qualification.
Water that has changed excessively by mixing with something that could have been avoided is not purifying, with the exception of earth and sea-salt even when thrown into the water.
Severely hot and cold water are disliked as well as water heated by the sun with it’s necessary preconditions.
A small amount of water previously used in an obligatory purification is not purifying.
2 qullahs of water do not become impure by mere contact with filth, though if the water changes it becomes impure. 2 qullahs roughly equal 500 Baghdadi Ritls. If the change disappears on its own or by water being added to it, it is again purifying. Less than 2 qullahs becomes impure, like any other liquid, by mere contact with filth, though dead creatures without flowing blood unintentionally thrown in and filth that cannot be seen are among the exceptions.
If the water reaches 2 qullahs through additional water and is unchanged, the water is purifying.
