The Stronger Position Regarding Small Amounts of Water and Used Water When Mixed with Impurity

Question:
The Honorable Shaykh, may Allah grant you success, asks: What is the stronger position regarding water less than two qullahs, and regarding used water? Do they become impure absolutely, or only if they are changed by impurity?

Answer:
There is a difference of opinion on this issue. its color, taste, or smell. This is the explicit text (manṭūq), whereas the hadith of the two qullahs is by implication (mafhūm). The explicit text takes precedence over the implication. Therefore, the stronger position among the most discerning scholars is that water does not become impure unless it is changed, whether it is a small amount or a large amount.
