The Ruling on Touching a Dog, a Pig, and a Donkey

Question:
Regarding touching a dog, a pig, and a donkey, is wudu' (ablution) obligatory from that, or is it sufficient to wash the hands only?

Answer:
And washing the hands is not required if the dog, pig, or donkey is dry; touching it does no harm, so there is no need to wash the hands, except for the sake of cleanliness only. However, if the dog is wet, meaning it has been affected by water and moisture, then yes, it is obligatory to wash the hands. Honorable Shaykh, may Allah grant you success, regarding the water that drips from air conditioners, do you know that people used to mix with dogs, especially if they were for guarding or hunting, and it was not mentioned that they used to wash their hands when they touched them or when the dogs touched them; this was not mentioned. They used to use donkeys and ride them, and it was not mentioned that they used to wash their hands. This is from the category of removing hardship from people. Yes.
