The Prophet heard that and said: 'Woe to you! Do you not know what happened to one of the children of Israel? If any urine touched any part of their clothes, they would cut that out with scissors. He told them not to do that, so he was tormented in his grave.'" (Da'if)Another chain with similar wording.

And Allah loves those who make themselves clean and pure." was revealed, the Messenger of Allah said: 'O Ansar! Allah has praised you for your cleanliness. What is the nature of your cleanliness?' They said: 'We perform ablution for prayer and we take bath to cleanse ourselves of impurity due to sexual activity, and we clean ourselves with water (after urinating). He said: 'This is what it is. So adhere to it.'"

Chapter 31: Washing a vessel that has been licked by a dog
'I saw Abu Hurairah hitting his forehead with his hand and saying: "O people of Iraq!

I bear witness that I heard the Messenger of Allah say: 'If a dog licks the vessel of anyone of you, let him wash it seven times.'"
The Messenger of Allah said: "If a dog licks the vessel of anyome of you, let him wash it seven times."
The Messenger of Allah said: 'If a dog licks a vessel, wash it seven times and rub it with dust the eight times."
