Humaidah bint Ubaid bin Rifa'ah narrated: "Kabshah bint Ka'b bin Malik - she was (married) with Ibn Abi Qatadah - narrated "That Abu Qatadah visited her, [so she said:] 'So I poured water for him to use for Wudu.' She said: “A cat came to drink, so he lowered he container until it drank.' Kabshah said: “So he saw me looking at it and said, "O my niece! Are you surprised at that?" So I said yes. He said: "Indeed Allah's Messenger said 'It is not impure, it is only one of those roam around among you””"
