What is the ruling on still water ('ma' واقف) adjacent to flowing water in a riverbed if the combined volume is less than two qullahs and one part is contaminated?
Chapter on what purification is achieved with regarding water
Al-Mughni
Book of Purification
Primary text
If still water adjacent to the flow, but separate from the main current, or water in a depression within the riverbed, connects with the flowing water, and the total volume is less than two qullahs, the entirety is considered impure if impurity is present in either portion. This is because the connection results in a single body of water below the two-qullah threshold, rendering it impure, similar to stagnant water.
