How to reconcile the hadith of the Well of Budha' with the statement that water becomes ritually impure if any of its characteristics change?

Question:
May Allah reward you. The Honorable Shaykh says: Regarding their statement that water becomes impure if its color, taste, or smell changes, how do we reconcile this statement with the hadith of the Well of Budha'?

Answer:
Change is of two types: change due to ritual impurity, and change due to something other than ritual impurity. If it changes due to ritual impurity, it is ritually impure by the consensus of the scholars. The second type of change is by something pure. It changes by something pure, but the name "water" has not been removed from it. The correct view is that it is purifying, that one performs wudu' with it, such as the Well of Budha'. It changed by something pure and the name "water" was not removed from it, so it is purifying according to the correct view among the scholars' opinions. However, if the name "water" is removed from it and it is no longer called water, as if tea is put in it and it becomes tea, or if someone says, "This is water," and another says, "This is tea," or if henna is put in it and it changes due to the henna, and it is not said, "This is water," but rather, "This is henna," or if dyes are put in it that transform it, then it does not purify, because the name "water" has been removed from it, even if what changed it was pure, because the name "water" has been removed from it.
