It was narrated that Jabir bin 'Abdullah said:
"We came to a pond in which there was the carcass of a donkey, so we refrained from using the water until the Messenger of Allah came to us and said: 'Water is not made impure by anything.' Then we drank from it and gave it to our animals to drink, and we carried some with us."
