Dog-spit Fatwa

This Friday's Fatwa comes via Blazing Cat Fur and the Assembly of Muslim Jurists of America:

Question. ... if I had wudu then a dog touched me can I pray or are all these just matters of Ijtihaad? ...

Fatwa. ...  it [dog-spit] is impure because of the hadeeth of the Prophet: “If the dog licks in your vessel then wash it seven times; one of which should be with soil.” ...

And if a Muslim licks your vessel ... sick your dog on him.
