Assalamu alaykum - As the brother Muhammad Nur said above, I read in The Guiding Helper which is consider authentic, that the dogs & even pigs are pure including their saliva. And the prayer offered with the clothes with their saliva, or urine is valid - w/o washing. With that being said, why is it haram to keep it as a pet, and what's the daleel for this? It seems to contradict the idea of dogs being pure. (How can taahir be haraam to pet.) Also, are there any Maaliki scholars who disagree with dogs being pure?? Is this what the Imam Maalik (Rahimahullah) said about the dogs?
