Purity: Purification of Well Water After Removal of Impurity’s Effect

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 43

If an impurity falls into a well and changes the water’s smell, colour, or taste, in the event that the change in the water disappears, it becomes pure. However, based on obligatory precaution, the water becoming pure is conditional on it mixing with the water that gushes from the well.
