48-1. طَھُور is on the pattern of fa‘ool in the sense of an instrument. That is, things by which purity is obtained, just as the water for ablution is called wudhu and fuel is called waqood. In this sense, water is tahir, pure in itself, and mutahhir, also purifying others. It is also mentioned in the hadith: ان الماء طهور لا ینجسہ شیء Abu Dawood. If its taste changes, then such water is impure, as mentioned in the hadith.
