Is it permissible to perform ablution with water that has changed [in its characteristics] due to something other than an impurity? And do the three descriptions pertain only to water that has become impure, or to all types of water?
Water that has changed (in color, smell, or taste) but remains pure [tahir] does not remove ritual impurity [hadath] nor does it cleanse impurity [khabath]. However, it can be used for ordinary customs like drinking and cooking. But if it has changed due to an impurity [najis], then it neither removes ritual impurity nor cleanses impurity, nor can it be used for ordinary customs.
