Volume 8, Book 73, Number 38:
Narrated Abu Huraira:
Allah’s Apostle said, “While a man was walking on a road. he became very thirsty. Then he came
across a well, got down into it, drank (of its water) and then came out. Meanwhile he saw a dog
panting and licking mud because of excessive thirst. The man said to himself “This dog is suffering
from the same state of thirst as I did.” So he went down the well (again) and filled his shoe (with wa –
ter) and held it in his mouth and watered the dog. Allah thanked him for that deed and forgave him.”
The people asked, “O Allah’s Apostle! Is there a reward for us in serving the animals?” He said, “(Yes)
There is a reward for serving any animate (living being) .”
