- The criterion (ḍābiṭ) for water losing its ability to purify is that it becomes dominated by the added pure substance.
This can occur in two ways, depending on whether the substance is solid or liquid:
(1) Mixing with Pure Solids: If pure solids are mixed with the water, causing the water to lose its essential property of being liquid and flowing, the water is considered overcome and can no longer be used for ritual purification.
- “Liquid” is the ability of water to be wrung from a cloth.
- “Flowing” refers to the way water normally moves along surfaces.
If the water remains fluid and retains its consistency but experiences changes in its characteristics due to mixing with solids, this does not affect its ability to purify—as long as the mixing was not through cooking. Examples include water mixed with saffron, soap, lentils, fruits, or tree leaves.
(2) Mixing with another Pure Fluid: When pure liquids are mixed with water, the validity of using the mixture for ritual purification depends on several factors: If the liquid differs from water in only one characteristic (such as taste or smell), the water becomes invalid for ritual purification if it adopts that characteristic. If the liquid differs in two characteristics (like colour and taste), the water becomes invalid if either characteristic transfers to it. For liquids that differ in all three characteristics (colour, taste, and smell), the water is invalid for ritual purification if two of these characteristics are adopted. Lastly, if the volume of the added liquid exceeds that of the water, it cannot be used for ritual purification, even if no changes in characteristics occur. If the volumes are equal, the mixture is considered dominated by the added liquid, and it is precautionarily invalid for ritual purification.
