(1) باب المياه
And Ashab As-Sunan (compilers of the prophet's sayings) reported that one of the wives of the Prophet (ﷺ) took bath from a vessel, then came the Prophet (ﷺ) and when he wanted to take bath from that (vessel), she said, "I was sexually impure". He said, "Water does not become sexually impure". [At-Tirmidhi and Ibn huzaima graded it Sahih (sound)]. (IT)
