Is water in a ghadir (a small pool left by a flood) that has been altered by the urine of animals purified according to the four madhhabs?

If the intended meaning of "يُطَهَّر" (with a Fatha on the Yā' and a Sukūn on the Ṭā') is the possibility of purifying the water of a pond, then if it changes due to the urine of an animal whose meat is permissible to eat, it is considered pure by the Malikis and Hanbalis because they consider its urine pure, but impure by the Shafi'is and Hanafis. In the case of its impurity, it is purified either by pouring a large amount of water onto it until the change disappears, or by drawing water from it until only unchanged water remains. The different madhhabs vary in preferring one of these two methods.

However, if the intended meaning is "يُطَهِّر" (with a Ḍamma on the Yā', a Fatha on the Ṭā', and a shaddah with a Kasra on the Hā'), meaning that the water purifies other things, then water that has changed in any of its three characteristics (color, taste, or odor) is not pure (ṭahūr), and therefore does not remove ritual impurity (ḥadath) or physical impurity (khabath). This is the view of the majority of scholars.
