Wudu with floodwater that has changed and with water changed by tea

Question:
And I said, O Shaykh, may Allah grant you success, it is known that if water is dissolved by something like tea, or the ablution, or the like, it is not permissible to perform wudu with it, nor is it sufficient for prayer, because the matter has changed. But we see that the waters of the seasons and of cattle are dissolved by something, which is the earth, so it most resembles clay, and yet wudu is valid with it. I hope you will clarify the difference between these two matters?

Answer:
It is not possible to guard against the change in floodwater caused by earth and trees; this cannot be guarded against. Is there any blame in that? If the water changes due to its course, or due to the flood soil, or due to trees that fall into it, or winds that blow trees into it, this cannot be guarded against and there is no harm in it. It is purifying, and praise be to Allah. The discussion is about waters into which something is intentionally thrown, such as trees, until it changes significantly; this is a matter for research.
As for what changes from its name to another name, one does not perform wudu with it. For example, tea and coffee; these are not called water, they are called coffee, they are called tea. If water changes from its name to another designation, it is not permissible to perform wudu with it, such as tea, coffee, or the like of the changes that have shifted from the name of water to another name. Yes. And Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad and upon his family and all his Companions.
