Purity: Ruling on Basin Water Connected to a Tank Reaching Kurr Volume

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 32

If the water of a basin in a public bath is less than kurr, and the water is connected to the water of a tank which together with the water of the basin equals kurr, in the event that the water of the basin comes into contact with an impurity but its smell, colour, or taste does not change, the water does not become impure.
